Topic: Analysis of cosmic ray events at the highest energy
Description: Pierre Auger Observatory is the largest experimental apparatus in the field of astroparticle physics. Particles with energies larger than that of the LHC beams are detected by the array covering 3000 square kilometres in the Argentinian pampa. These cosmic particles originate in yet unknown sources in the Universe. The Aim of the Observatory is to measure the energy spectrum, direction of the incoming particles and answer the question about their chemical composition. New analysis techniques at the Observatory will be developed by the student as well as new emerging detection techniques of cosmic rays will be investigated.

Topic: Modern methods of evaluation of optical elements
Description: The topic is focused on the development and application of selected optical topographic methods or their combinations on non-standard large-scale surfaces as control methods for assessing the quality of these areas and for correlation research between the technological process and the qualitative and quantitative product parameters. Furthermore, it is assumed that the research findings will be applied directly to available optical production technologies, especially new generation ones. This topic is chosen broadly due to the fact that the theme will be concretized to the expected customer according to actual necessity of solving this problem in the Joint Laboratory of Optics of Palacky University and Institute of Physics of the Czech Academy of Sciences, possibly in cooperation with foreign partners and in accordance with the student's individual orientation and abilities.

Topic: Acoustic wave analysis for exploring the physical properties of surfaces
Description: Acoustic waves emitted during the mechanical tests at the nano-micro scale are a rich source of information about the deformation behavior of the tested material. Analysis of acoustic emissions provides a better understanding and more complex interpretation of the results obtained by the nanoindentation and scratch test. The topic encompasses an experimental testing of local mechanical and tribological properties of surfaces and a theoretical and experimental analysis of acoustic emission signals. In particular, the adaptation of classical macroscopic acoustic emission approaches to micro scale for exploration the formation of micro cracks, delamination or phase transformations of thin films, coatings, and micro objects.

Topic: Complete characterization of strip silicon detectors developed for the ATLAS Inner Tracker by using testbeams and computer simulations
Description: The Large Hadron Collider accelerator at CERN will be upgraded to the High-Luminosity Large Hadron Collider (HL-LHC) machine between 2024 and 2027. The instantaneous luminosity of the HL-LHC will reach 7×1034 cm-2s-1, corresponding to an average of 200 inelastic proton-proton collisions per bunch crossing, and the total integrated luminosity delivered to the ATLAS experiment will be higher than 4000 fb-1. Parameters of the HL-LHC accelerator thus imply high requirements on radiation hardness, granularity, as well as the speed of data transfer and data processing of the inner tracking detector. The current inner detector of the ATLAS experiment will be replaced by the completely new all-silicon Inner Tracker (ITk), which will consist of pixel and strip silicon detectors. The main topic of this doctoral thesis is a detailed characterization of detection properties of strip silicon detectors developed by the ATLAS ITk collaboration. This characterization will be performed by using testbeams of ultrarelativistic electrons and hadrons at DESY II and CERN SPS synchrotrons using the EUDET beam Telescope built from several pixel silicon detectors located in front of and behind of the tested sample. The recorded experimental data will be compared to outputs of computer simulations prepared in Allpix Squared and Athena simulation frameworks which provide libraries to simulate a complete testbeam experiment, starting from the calculation of energy deposited by a charged particle passing through the silicon sensor to the signal digitization in individual readout channels.

Topic: Synthesis of 1D structures and their decoration using plasma techniques
Description: Synthesis of arrays of 1D nanostructured semiconducting materials is an important topic in materials research due to their very high surface to volume ratio, robust chemical and environmental stability and less charge carrier recombination. Nanostructured 1D materials can be further functionalized with the decoration of another semiconducting or metal nanostructure by plasma-based technique or by chemical-based technique. Those functionalized nanostructures can be highly advantageous for various applications including sensors, battery or supercapacitors, etc. In the proposed research work, we want to study the formation of 1D nanostructured materials of metal oxides by chemical as well as plasma-based techniques. These functional 1D nanomaterials will be grown by hydrothermal as well as by electrochemical anodization-based processes. For enhancing the crystallinity of those 1D materials thermal annealing will be carried out. Furthermore, the functional properties of these 1D nanomaterials will be further tuned by decorating another functional material by means of either magnetron sputtering or chemical or electrochemical based processes. In particular, the effort will be devoted to the relationship between physical and chemical properties of created structures and conditions of technological processes as well as their applicability in various fields.

Topic: Physical properties of multifunctional thin films
Description: Metal and metal oxide semiconductor thin film fabrication gaining tremendous research interest due to its applicability in optoelectronic devices as a charge carrier transport layer, various types of sensors as well as a transparent conducting oxide. The chemical, optical and optoelectronic properties of the metal oxide thin films depend on several parameters for example thickness, crystallinity, different types of defects as well as the surface morphology of the thin films. The research topic combines the fabrication of multifunctional metal and metal oxide thin film fabrication by physical vapor techniques (thermal evaporation, magnetron sputtering, reactive magnetron sputtering) and experimental testing of structural, compositional characteristics. The functional properties of those films will be further tuned by means of plasma treatment and the thermal annealing process. The optical, electrical and optoelectronic properties of those thin films will be characterized using various sophisticated analytic technologies. Furthermore, the applicability of those thin films will be studied as a flexible chemo-sensor or photodetector.

Topic: Analysis of cosmic gamma ray events in the CTA experiment
Description: The Cherenkov Telescope Array Observatory (CTAO or CTA) is going to be the largest and technically most advanced ground-based facility for detection of high-energy cosmic gamma rays. CTA will be located at both the southern and norther hemisphere. Both locations will be equipped with three types of telescopes covering three ranges of energies of the incoming gamma photons. The ultimate sensitivity will span energies from 20 GeV to 100 TeV. The detection principle is based on detection of Cherenkov light in the telescopes generated by charged particles traversing a medium with a speed greater than the actual speed of light in the given medium, i.e. in atmosphere. The charged particles are created in cascades of interactions whose onset is the primary interaction of the incoming gamma photon with atoms in the atmosphere. The envisaged work is supposed to cover the tasks of analysis and interpretation of the measured data. The primary task of CTA is to measure the energy spectrum and distribution sources of the gamma photons.
