Laser-Induced Breakdown Spectroscopy (LIBS) method enables elemental analysis of a sample in any state of matter (solid, liquid, gaseous). Basic principle of this method is essentially bound to the ablation of material in the interaction region as a consequence of the impact of high power laser pulse (so called laser-matter interaction). Laser-Induced Plasma then emits characteristic emission which might be related to the sample composition. Wide range of characteristic spectral lines is present in the visible spectral range, this enable the utilization of conventional spectrometers. However, spectral lines of certain elements (C, N, S, P, Cl, Br) are typically found in the VUV region (<200 nm). Their detection is therefore non-trivial and demands specific and more complex instrumentation, which avoids the absorption of VUV emission in ambient air (mostly oxygen). The scope of this thesis is then in design and implementation of a spectrometer with detection ability enhanced in VUV range to the current device and further investigation of Laser-Induced Plasma formation under vacuum conditions.

Kelvin's probe force microscopy (KPFM) is an excellent tool for mapping the distribution of surface potential locally up to nanometer resolution. This can be advantageously used in a study of charge distribution on nanometer-sized sensors and at investigation of p-n interfaces of solar cells during their operation. This new information, in addition to commonly studied sensor current responses and solar cell voltage responses, makes it easier to understand the ongoing physical processes, use this knowledge to eliminate the shortcomings of existing devices, and possibly to design higher efficiency devices. At work, you will need to master the general physical principles of KPFM, sensors and solar cells. A suitable applicant is a graduate of a Master's degree in Physics, Electrical Engineering or Chemistry.

The aim of the dissertation thesis is instrumental and methodological development in cryogenic scanning electron microscopy (cryo-SEM). Significantly hydrated samples can be physically fixed (very quickly frozen) into amorphous ice just under certain conditions, where during the freezing process the crystallization does not have time to occur (typical limiting factors may be the temperature of cryogen, speed of freezing, the sample thickness, etc.). For these purposes, number of techniques were developed such as plunging into liquid ethane, propane-jet. So far the most sophisticated freezing technique is the use of the liquid nitrogen under high pressure (high-pressure-freezing; HPF). Thus, part of this work is development of a system based on freezing of small volumes using microfluidic chips that can extend cryo-EM techniques to in-situ experiments and could be the bridge between classical freezing techniques and HPF. Newly developed cryo-techniques will be further adapted to cryo-SEM method of freeze-fracture and consequently applied to biomedical samples.

Dual-energy computed tomography (DECT) is a modality that was formerly used only at synchrotron based facilities. Recently it has been used in medical sphere of computed tomography (CT) and nowadays potential of DECT has been tested on laboratory based CT system with high resolution. This technique uses two energetically different X-ray spectra for examination and specific differentiation of individual sample components, in terms of materials or tissues, based on their attenuation properties. This differentiation is feasible even for materials which would be inseparable in CT data from standard CT measurement using only one beam energy. Therefore, an advantage of DECT is a possibility of precise material segmentation and classification. Furthermore, acquired information from DECT measurement can be utilized for creating pseudo-monochromatic CT images which results in specific reduction of tomographic artifacts e.g. beam hardening. Aim of this thesis will be study of DECT technique and testing its potential and utilization in sphere of laboratory CT system with submicron spatial resolution.

The project will involve microscopy techniques, cell culture, capillary microinjection, computer image processing and data analysis.
GaN is namely due to its wide direct gap (3.4 eV) a perspective material for semiconductor industry. Such a material can be prepared in form of thin films, but also as nanwires and nanocrystals. It is reasonable to expect that by its space confinement new physical properties might be expected. The study will be aimed at fabrication of spatially restricted nanostructures (nanowires, nanocrystals), their analysis and a study of physical properties
The graphene-Si interface creates a Schottky junction being a perspective structure for the design of solar cells and fabrication of very sensitive gas sensors. To analyse such an interface in a complex way, surface and interface analytical methods such as SPM, SEM, TEM, Raman and FT-IR micro-spectroscopy, etc. should be used. The study will be aimed at the design and optimisation of electronic devices based on the Schottky junction.
Due to their geometry, one-dimensional materials seem to be natural building blocks for many device systems, e.g. in electronics or photonics. Because of high surface-to-volume ratio there is a need to analyze the properties of surfaces (ether electronic, morfology etc.) by surface-sensitive techniques. However, these often lack spatial resolution. The aim of the disseration work is to study the surfaces of relevant nanomaterials (with emphasis on quasi-1D semiconductors and oxides) and correlate them with projected functional properties (e.g. optical – fotoluminiscence etc.).
Recent scanning electron microscopes are equipped with sophisticated detection systems enabling effective energy and angular filtering of the secondary electrons. There are only a few practical applications of this technique, e.g. mapping of dopants in semiconductors and study of polymers composition. Applications in the field of metals and alloys do not exist yet. The goal of the thesis is an investigation of the possibility of the secondary electron filtering in commercial instruments and application of this technique for the study of metals and alloys. As the next step, a novel detector design will be proposed and tested on selected materials.

Revealing the growth mechanisms at nanoscale is particularly challenging from many reasons. The most prominent advances in physics of nanostructure growth were achieved utilizing real-time in-situ monitoring techniques (both microscopic and spectroscopic). In our group, we have a large expertise in real time electron microscopy and, in the following year, we will install a new vacuum chamber dedicated to Fourier transform Infrared spectroscopy. The aim of this PhD dissertation is to work on revealing puzzling growth modes of different nanostructures of interest (semiconductor nanowires grown by MBE, metallic/oxide threedimensional nanostructures formed by Focused Electron Beam Induced Deposition etc.) utilizing state-of-the-art equipment. Close collaboration with ThermoFisher Scientific R&D labs will be part of applicants work.

The thesis will deal with the research and the development of new analytical approaches in low-energy ion scattering – LEIS, which is often used for the analysis of purity of the surfaces as well as for the depth profiling of thin layers. The final energy of detected ion contains information about the elemental composition of the studied surfaces. Utilization of the sputtering of the surface, measured energy spectra yield information about the elemental distribution in the depth of the sample. LEIS can be combined with the SIMS (Secondary Ion Mass Spectrometry) method to exploit the strengths of both methods, sensitivity and quantifiability. The thesis will aim for development of new simulation and experimental methods enabling the intermediate interpretation of measured data and their further application in analysis of surface structures.

In the study plasmonice nanostructures of novel materials (for instance graphene) for detection of adsorbed complex (bio)molecules by FT IR spectroscopy will be used. Instead of relying on classical spectral shifts of localized surtface plasmon polaritons, the „finger prints“ of the molecules in optical spectra enhanced by plasmonic effects will be detected. Here, particularly, tunability of plasmon resonance properties of the nanostructures will be utilized.
The fluorescence holographic microscope, unlike a conventional fluorescence microscope, uses two opposed objective lenses and it requires no scanning system. In addition to a well known optical sections (amplitude image), it also provides a phase image revealing information about the optical density of the specimen. Although the microscope is primarily intended for transparent samples capable of emitting radiation (eg fluorescence), it can also be used for holographic imaging of reflective surfaces or for holographic imaging in transmitted light. The task includes the selection of suitable sample types, experiment protocol proposal, design and implementation of accessories for sample preparation, accomodation, fixation and storage in a suitable environment, and sample manipulation during the experiment, experiment control, and testing of the microscope imaging possibilities for different sample types, and publishing results. The aim of the thesis is to find limits of the microscope and to maximize the use of all the imaging capabilities of the microscope and find the most suitable applications for this new imaging technique.
Applications of tools of informatics, computer science and numerical mathematics for the description of motion of an electromagnetic pulse in dispersive medium. This approach shall be exiting from the solution of an equation describing these sorts of waving, which is identical, from the mathematical point of view, with the relativistic wave equation. It is possible to make an effort to apply the Vainshtein generalized definition of the group velocity of a pulse, eventually another definitions of this velocity, to various types of dispersive media and to different types of input pulses. The applications is expected in the pulse transfer of informations for example in waveguides, optical fibres and optical cables, especially in the case of the nanosecond pulses.

The aim of the dissertation thesis is instrumental and methodological development in the field of low temperature scanning electron microscopy (SEM), which will include the design of an optimal construction for the sample cooling within the SEM including an anticontamination system. Part of the work will be the development of methodology for the preparation and imaging of hydrated samples sensitive to the electron and ion beam irradiation. A design of procedures for the processing of measured data obtained from a large sample volume will be included. Methods will be applied primarily to biological samples and their combinations with nanoparticles, which play an important role in medicine, pharmacology etc.
Imaging at several millimetres depth in tissue, while maintaining the sub-micron resolution available in standard light microscopes, requires new types of endoscopes. Multimode fibers have shown promise as flexible endoscopes, but advanced adaptive optics is needed to overcome the phase offsets between the propagation modes in the fiber, which scrambles the image. In this project we aim to implement multi-photon fluorescence and non-linear Raman microscopy (SRS or CARS) at the end of a multimode fiber endoscope. Initially, the student will study the frequency dependent light transmission in graded index fibers (experiments and theory), with the aim to allow delivery of femtosecond pulses. Once this is achieved, we will apply this to multi-photon imaging and investigate the possibility of non-linear Raman imaging. We will evaluate which method (SRS or CARS) is more suitable for imaging through a multimode fiber. Towards the end of the project we hope to demonstrate label-free non-linear imaging in tissue. This has potential use in diagnosing tumours in situ without performing a biopsy. The project is mainly experimental with only some (<20%) theoretical modelling. The student will learn basic modelling of light propagation in an optical fiber, adaptive optics, microscopy and imaging, programming for instrument control, femtosecond pulse characterization techniques. Knowledge of optics is central to the project. Some knowledge of a programming language (Matlab, LabView or similar) would be useful. The work will take place at the Institute of Scientific Instruments of the Academy of Sciences of the Czech Republic with the possibility of full-time employment. The PhD student will be a part of the research project “Gate2mu: Holographic endoscopy for in vivo applications", which is currently running at this institute. The whole Gate2mu project will consist of ca 15 people (post-grads, postdocs and several senior researchers).
Cancer invasion and metastasis is the major cause of mortality and morbidity in cancer patients. The main problems lie in accuracy of diagnosis and the choice of the most efficient treatment. Better utilisation of biopsy material is a promising candidate for improvement. This project focuses on development of a new procedure where the biopsy fragments from cancer patients will be subjected to time-lapse analysis of 3D cell motility based on 2-photon imaging featuring deep penetration. Motile behaviour of cells within the fragments will be quantitative analysed and statistical significance of changes induced by presence of potential chemotherapeutic agents will be evaluated thus indicating a suitable treatment for the relevant patients.

Coherence-controlled holographic microscopy is focused on the observation of living cells in vitro. Long-term observation of living cells necessarily requires automated control of both microscope and experiment. The first goal is to design a new optical arrangement of a fully automated microscope, its mechanical design, and creation of the control software. Another goal is to propose methods for automation of biological experiments, implementing them into control software, and testing in real experiments.
Tightly focused laser beams can act as optical "tweezers" to trap and manipulate tiny objects, from nanoparticles to living cells. The development of this method has earned Arthur Ashkin the last years Nobel prize in physics. Most experiments thus far have been carried out in air or liquid. Due to an increasing interest of quantum technologies, employing the optical tweezers to trap objects in ultra-high vacuum (see the figure) became one of the interesting goals of scientists around the world. Such an isolated particle behaves as a very weakly damped mechanical oscillator whose energy can be easily removed and thus “cooled” eventually to the quantum ground state. Moreover, optically trapped objects exhibit, not only, unprecedented sensing performance (they can sense very weak gravity, electric and magnetic forces), but can also be used to study fundamental processes of nanoscopic heat engines, or quantum phenomena involving large masses. The main goal of the proposed PhD thesis will be to study optomechanics of single and multiple nano-particles optically trapped in vacuum, shaping the optical potential and employ such an isolated object to act as ultra-sensitive sensor at various scenarios. For instance, object optically levitated near a substrate surface can act as an atomic force microscope (AFM) but with extremely high sensitivity (pN vs zN). The PhD student is expected to perform the experiments, analyzed and interpret the results. The Institute of Scientific Instruments of the CAS (www.isibrno.cz) will provide all material conditions for this work for 4 years, has 20 year history in optical micro-manipulation techniques, collaborates with a number of laboratories around the world and belongs to the leading world-wide players in the this area (http://www.isibrno.cz/cs/mikrofotonika).

Correlation and holographic imaging are techniques that allow either quantitative phase or three-dimensional image reconstruction from interference pattern. The doctoral thesis aims to implement new configurations for correlation and holographic imaging, where the light is multiplexed into orthogonal polarization states rather than divided into independent optical paths. Such systems are expected to improve existing and provide new imaging features, which are unavailable in up-to-date experiments. The required polarization states will be generated and modulated using electro-optic effect in liquid crystal molecules or new generation optical components working on geometric phase.
The discovery of graphene, the substance becoming quickly an intensively studied material due to its unique structure and related properties, has led to an increasing interest in so called two-dimensional (2D) materials such as h-BN, MoS2, WS2, etc. The PhD study will deal with the preparation, analysis and application of these 2D materials, including the structures based on their combination.

Artificial frustrated magnetic systems provide powerful experimental platform to explore directly in real space exotic effects, which do not exist in nature or which would be too difficult to study otherwise. The aim of this PhD project is to fabricate 3D lattices of interacting magnetic nanostructures to investigate properties of two intermixed spin liquid states. The main scientific question is how the interface between the two spin liquid evolves as the system energy is minimized. The student will work on modelling, fabrication and analysis of the samples. The study will be done under double supervision in the regime of the shared “cotutelle” PhD study at the NÉEL Institute CNRS – Université Grenoble Alpes and at the Institute of Scientific Instruments in Brno. The student is expected to spend three 5 months cycles at Institut NEÉL in Grenoble. The length of study is adapted to 3 years because of the “cotutelle” programme. The sample fabrication will be made at the ISI, in Brno by utilizing electron beam lithography techniques. The investigation of the magnetic properties, as well as their modelling, will be done at IN, in Grenoble.

Low Energy Ion Scattering is well known for its extreme surface sensitivity. Its application is essential when the topmost atomic layer determines behaviour of various functional systems (catalysis, initial states of oxidation, graphene based systems, magnetic films, etc.). The proposed topic offers an exploitation of LEIS surface sensitivity in combination with other analytical and imaging techniques like for instance XPS, SIMS, AFM, and STM for a study of selected systems.
A study of the influence of the magetic field on the propagation of surface plasmon polaritons. Exploitaion of this phenomenon in the field of sensors and detectors.
The PhD study will deal with the effect of strong coupling between the localized surface plasmons in antennas and the excitations in their resonantly absorbing non-metallic environments. The main task will be to exploit this knowledge for finding and utilizing general principles of localized plasmon-enhanced absorption. We intend to tackle this problem over a wide electromagnetic spectrum, ranging from the mid-IR to the visible. Such a broader approach is possible due to common features of index of refraction at anomalous dispersion related to absorption peaks/bands of materials, regardless the physical origin of resonant absorption. We propose to go beyond the nowadays knowledge and limits on optimization of localized plasmon-enhanced absorption upon the strong coupling regime over a large spectral area. It will make it possible to carry out research on challenging phenomena exploitable not only in the local heating of materials, but also in IR and light detection, energy harvesting, (bio)sensing, etc.
The thesis will deal with the study of matrix effects in the field of Low Energy Ion Scattering (LEIS) and Secondary Ion Mass Spectrometry (SIMS). These methods can be used to perform elemental analysis of the upper atomic layer as well as the layers deep below the surface if the sample surface is sputtered. However, quantification of elemental composition is often difficult due to matrix effects. The doctoral thesis will focus on the development of new quantification approaches eliminating these matrix effects by combining the experimental data of both methods.

Fibre optics is experiencing unprecedented developments in both experimental and theoretical areas nowadays. Recently, for example, image transmission has been demonstrated by multimode fibre resilient to fibre deformation, as well as manipulation by microscopic objects using light transmitted by the fibre. New types of fibers with complex internal structures are also being developed. Very promising is the use of optical fiber as a specific time response element that promises applications in spectroscopy. The PhD student will initially learn the fiber optics methods, measurement of the transformation matrix, creation of required input states using spatial light modulator (SLM) and imaging by the fiber. Then he/she will focus on the time response of the fiber based on measurement of the frequency dependence of the transformation matrix. The result will be used to generate pulses with specific properties that behave in the fiber in the desired way. Based on this knowledge, the student will try to develop new spectroscopic methods using optical fibers. The work will include the theoretical and experimental parts. Knowledge of some programming language (Matlab, Mathematica, Labview, etc.) for the calculation and management of experiments will be very useful. The work will take place at the Institute of Scientific Instruments of the Academy of Sciences of the Czech Republic with the possibility of full-time employment. The PhD student will be involved in the project "Holographic endoscopy for in vivo applications", shortly Gate2mu, which is currently running at this institute. The whole Gate2mu project will consist of ca 15 people (PHD students, postdocs and several senior researchers).
