Profile
The curriculum concentrates on the comprehensive study of materials properties and failure processes from the point of view of physics and physical metallurgy. Students should develop capability to apply their knowledge in inventive manner to new technologies and materials, such as plasma spraying, special methods of thermo-mechanical and thermo-chemical treatment, etc. Special attention is paid to the degradation processes and to the synergetic effects of various materials properties on material failure. The subjects of study are metallic and non-metallic materials, e.g., structural ceramics, polymers, amorphous and nanocrystalline materials and intermetallics. The Ph.D. programme requires proficiency in mathematics and physics at the MSc. degree level obtained from Faculty of Science or Faculty of Mechanical Engineering.

Issued topics of Doctoral Study Program
By using Kelvin Probe Force Microscopy (KPFM) information on local electronic properties (e. g. surface potential, work function) of two-dimensional nanostructures can be obtained. This information can be used for understanding of physical principles, design, sensitivity/effectivity improvement of solar cells and sensors based on the 2D nanostructures. In the project, the Kelvin Probe Force Microscopy will be used e. g. for study of p-n junction in solar cells and charge transport observation in sensors based on graphene.

The LIBS technique utilizes the high power-densities obtained by focusing the radiation from a pulsed laser to generate in the focal region a luminous micro-plasma from an analyte. The micro-plasma emission is subsequently analyzed by spectrometer. The plasma composition is representative to the analyte's elemental composition. LIBS allows to reach high spatial (limited by the size of the laser beam diameter) and depth resolution (in the range of about some tens of nanometers). Detection limits are in the range of few tens ppm; for several elements even lower limits could be realized combining LIBS and laser-induced fluorescence spectroscopy (LIFS) techniques. In the dissertation work the automatization of the LIBS and LIBS+LIFS setups will be addressed. A computer code should be worked out for controlling all equipments and allowing automatic 2D and quasi-3D analysis of sample chemical composition. The function of automatized setups will be verified on selected samples.

Development of the control unit of piezoceramic annomanipulators and actuators. These elements will be used as a part of SPM or measuring or litografic stages.
Sample imaging in scanning transmission electron microscope (STEM) or transmission scanning electron microscope (TSEM) are standard microscopical techniques. But they can be also used for determination of aberration coefficients which is based on computer processing of amorphous sample images. The knowledge of the aberration coefficients is necessary for alignment of corrected electron microscopes. The standard approaches are based on Ronchigram - shading image of the specimen measured on 2D pixel detector behind the sample. The aberration coefficients can be determined from one or low number of Ronchigrams. If the microscope is not equipped by this detector the aberration coefficients can be determined from form series of diffractograms - Fourier transformations of amorphous specimen images with different sample tilt. The work will be concern on development and optimization of the method for system with 2D segmented detector behind the sample. It will cover design, simulations and experimental verification of the method.

Ion Beam Assisted Deposition (IBAD) of thin films ZrO2, HfO2, Al2O3, hydroxylapatite.
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.
