Issued topics of Doctoral Study Program

  1. Deep neural networks and their usage for defect recognitions on a surface of electronic structure

    The work deals with the use of neural networks with deep learning to diagnose the surface of electronic micro and nano structures that are scanned using electron microscopes with varying degrees of resolution. Search for defects occurring on the surface is time-consuming.

    Tutor: Sedlák Petr, doc. Ing., Ph.D.

  2. Development of piezoelectric lead-free materials for energy harvesting

    Nowadays, energy harvesting is very popular. Piezoelectric ceramic generators play a vital role in this field. Commercial piezoelectric generators (energy harvesters) are based on lead piezoceramics. A trend is to replace lead-based materials by lead-free materials. BCZT and BT are very perspective lead-free piezoelectric ceramics materials. The work is therefore focused on the development and study of these unleaded materials and their controlled doping for the purpose of efficient electric energy harvesting. Internship at the University of Oulu is planned.

    Tutor: Holcman Vladimír, Ing., Ph.D.

  3. Dielectric spectroscopy of materials with high permittivity

    Materials exhibiting high permittivity (dielectric constant, k) are needed for new applications, particularly in integrated circuits (ICs) using the 32 nm technology and in capacitors. In capacitors, high-k dielectrics are used in order to attain higher energy densities in capacitors and thus to reduce the size of capacitors themselves.

    Tutor: Holcman Vladimír, Ing., Ph.D.

  4. Electrical characterization of nanostructures by SPM

    Low-dimensional electronic structures demands sensitive characterization techniques. Wrong choice of measurements method can affect the nanostructures, modify its properties. Furthermore, ambient conditions influence the measurement and making additional complications in interpretation of the results. The objective of this study is non-destructive investigation of local electrical properties of nanostructures, including correlation between mechanical and electrical contrast of SPM-data. The result of the work should be the development of methods and calibration samples for the quantitative assessment of electrical parameters.

    Tutor: Sobola Dinara, Mgr., Ph.D.

  5. Energy harvesting devices based on lead-free piezoelectric materials

    The work deals with design, fabrication and optimization of energy harvesting devices based on piezoelectric materials. The main aim will be focused on lead-free piezoelectric materials such as BCZT, KNN and BNKT. Next part of this work is focused on design of electronics for proposed energy harvester devices with effort to obtain maximal energy transport from energy harvester into an energy storage. Last part is based on proposal and developing of suited methods for testing and evaluation of parameters for piezoelectric energy harvesters.

    Tutor: Sedlák Petr, doc. Ing., Ph.D.

  6. Flexible and bulk piezoceramic energy harvesters

    The aim of work is to develop new and innovative designs based on millimeter or nanometer piezoceramics for energy harvesters based on mechanical excitations (movement, vibration, motion wind etc.) The individual energy harvesters will be manufactured in a cooperation with selected departments within the university.

    Tutor: Sedlák Petr, doc. Ing., Ph.D.

  7. Fluctuation processes of graphene based structures

    Low-frequency noise processes are observed in many electronic components/devises. Generally, it is associated with the sample local/volume electrical stress, aging effects and possible structural imperfections. The 1 / f noise is dominantly observed, which in combination with the 2D graphene structure provides a unique opportunity to study the actual noise process as well as the properties of modern electronics based on graphene (transistors, sensors, etc.).

    Tutor: Macků Robert, Ing., Ph.D.

  8. Impact of microstructural defects on charge transport in chalcopyrite-based solar cells

    Solar cells with chalcopyrite absorption layer Cu (In, Ga) Se2 as a modern photovoltaic technology suffers a huge variability of defects in commercial production with negative consequences for separation and subsequent transport of charge. Therefore, in this multi-component system, direct assignment of electrical or optical manifestations of point defects is difficult. The thesis will be focused on searching of individual microstructural defects of size (1–10) µm by scanning electron microscope in combination with cross-section analysis using focused ion-beam and material analysis by energy dispersive spectroscopy. The aim of thesis is to link physically founded defects with specific manifestations of electro/optical characterization and to broaden general knowledge of point defect behaviour for thin-film technologies.

    Tutor: Macků Robert, Ing., Ph.D.

  9. Increase of dielectric constant for ceramic materials for use in capacitors

    High permittivity materials are needed for new applications, eg. in the next generation integrated circuits or in capacitors. In the manufacture of capacitors, materials with high permittivity are desirable to achieve a higher density of energy in the capacitor and hence to diminish the dimensions. Nowadays, pure BaTiO3 material is used for commercial ceramic capacitors. By doping the permittivity of this material can be increased up to 10 times. The aim is to find options for BaTiO3 to increase the permittivity in the form of doping or material modification. Internship at the University of Oulu is planned.

    Tutor: Holcman Vladimír, Ing., Ph.D.

  10. Influence of electrode morphology on electric charge transport at electrode / electrolyte interface

    The aim of this work is to study the charge transport at electrode and electrolyte interfaces, with an emphasis on the analysis of the influence of morphology on sensory properties (selectivity, sensitivity, etc.). Practical results lay in development of physical and electrical models on the basis of experimental study of amperometric gas sensors.

    Tutor: Sedlák Petr, doc. Ing., Ph.D.

  12. Preparation of BiFeO3 by sol-gel method

    The sol-gel method consists in converting a sol (water solutions of bismuth and iron nitrates) into a gel by hydrolysis and condensation. Sol-gel method allows preparation of materials with sizes from ceramics samples to individual nanoparticles (up to 30 nm). Bismuth ferrite thin films BiFeO3 (with a thickness or dimension of crystallites up to 62 nm) are of interest because of the possibility of obtaining a magnetoelectric effect. The aim of the work is to study the properties of BiFeO3 films obtained by the sol-gel method depending on the temperature and time of synthesis. The chemical homogeneity of the obtained material, which is advantage of this method, makes easer the work on the study of structural characteristics.

    Tutor: Sedláková Vlasta, doc. Ing., Ph.D.

  17. Synthesis and properties of multiphase Bi-Fe-O thin films

    The objective of this study is influence of preparation parameters on structural properties of Bi-Fe-O system. Phase variation depends on method and chosen parameters of thin films formation. Pulse laser deposition of Bi-Fe-O films from BiFeO3 target (with higher chemical and phase purity) is supposed to be used for preparation of the films. This technology allows obtaining high-quality heterostructures and excluding the presence of impurities. Currently, there is no complete information about the nature of the phase formation of Bi-Fe-O compounds. Materials on the basis of Bi-Fe-O are important for design of sensors, memory devices other applications of nanotechnology. Control of phase purity of Bi-Fe-O thin films is supposed to be studied in correlation with magnetic and electrical properties.

    Tutor: Sobola Dinara, Mgr., Ph.D.

  18. Utilization of electromagnetic emission for monitoring of processes in rocks

    Electromagnetic emissions (EME) arises during mechanical loading of solids. EME anomalies under natural conditions can be observed in association to tectonic loading, stress re-distribution and crack propagation prior to earthquake or in relation to gravitational mass movements. EME can be measured by various types of sensors and antennas and it is possible to perform monitoring of the above mentioned phenomena based on this measurement. The goal will be development of a methodology for measuring and processing of EME for use in predicting of earthquakes and other selected events and possibly to distinguish between different types of these phenomena. Long-term measurements of EME in caves in the Czech Republic and in the Alps in Austria will be carried out for this purpose and the results will be compared with results from other methods used in geology. Analysis of EME signals origin and propagation in studied materials and design and verification of advanced methods for measured signals processing and evaluation will be an important part of the work. The Ph.D. student will cooperate on the scientific research collaboration with the Institute of Rock Structure and Mechanics of the ASCR.
