List of suggested theses
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: 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.

Topic: Physical properties of multifunctional thin films
Description: The research topic combines the fabrication of multifunctional metal, metal oxide and nitride thin films by physical vapor techniques (thermal evaporation, magnetron sputtering, reactive magnetron sputtering) and experimental testing of their structural and 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: Synthesis of 1D structures and their decoration using plasma techniques
Description: The research topic covers mainly 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.
