Characterisation of Nanostructure Deposited by PVD and CVD Technology
Fořt, Tomáš ; Boušek, Jaroslav (referee) ; RNDr.Vilma Buršíková, Ph.D. (referee) ; Sobota, Jaroslav (advisor)
The thesis deals with mechanical properties of thin hard wear-resistant coatings. The work presents a method of dynamic testing of thin hard coatings on a newly constructed prototype of impact wear tester. It provides a comparison with standard methods of layer testing and presents new experimental results of dynamic impact wear test of the coatings. Finally, the thesis covers preparation techniques of thin film systems deposited on various substrates and their characterization using optical and electron microscopy.

Workplace for testing of solar cells using LBIC method
Harašta, Tomáš ; Jandová, Kristýna (referee) ; Fořt, Tomáš (advisor)
Subject this diploma thesis is introduction to solar problems, with folow-up focus on solar elements and reflection about their defects. The next part is dedicated diagnostic method LBIC (Light Beam Induced Current) that help to detect defects of solar elements. The work is concerned with aplication this method in general view, from construction of workplace, throuhg hardware to software. The last part is focused on results processing and analysis.

Reactive sputtering Al2O3
Dušek, Jan ; Boušek, Jaroslav (referee) ; Fořt, Tomáš (advisor)
Diploma thesis describes technology of pulse reactive magnetron sputtering of Al2O3 coating. Furthermore it deals with design of deposition process and testing new aluminium target. The technological window was determined by tests. As a result, it was possible to create Al2O3 coatings in the widest possible working range. The coatings created by apparatus PLS 160 were tested for optical properties in order to obtain transmittance. Besides the optical tests, the evaluation of mechanical properties and adhesion were performed. The obtained results from measurement were evaluated. Based on the results, some possible applications of the coating were suggested.

Thermal stability of Ti/Ni multilayer thin films
Václavík, R. ; Zábranský, L. ; Souček, P. ; Sťahel, P. ; Buršík, Jiří ; Fořt, Tomáš ; Buršíková, V.
In this work, thermal stability and mechanical properties of Ti/Ni multilayer thin films were studied. The multilayer thin films were synthesised by alternately depositing Ti and Ni layers using magnetron sputtering. The thickness of constituent layers of Ti and Ni varied from 1.7 nm to 10 nm, and one coating was deposited by simultaneous sputtering of both targets. Single crystalline silicon was used as a substrate. The effects of thermal treatment on the mechanical properties were studied using nanoindentation and discussed in relation to microstructure evaluated by X-ray diffraction. Annealing was carried out under low-pressure conditions for 2 hours in the range of 100-800 degrees C.

Dissent in the Baltic republics
Fořt, Tadeáš ; Švec, Luboš (advisor) ; Kolenovská, Daniela (referee)
Tadeáš Fořt Abstract This bachelor thesis deals with the differences between dissent in Lithuania, Latvia and Estonia. All groups of dissidents were influenced by international events such as revolution in Hungary in 1956, Prague spring of 1968 and the signing of the Helsinki Final Act by the Soviet Union. Even though all dissident groups reacted to those events, the form and motivation of their protests against the regime were different. Main differences between these groups lie in national and religious differences in Baltics. While Lithuanians did not have an issue with immigration from other Soviet countries, Latvians and Estonians were becoming minorities in their own countries which heavily influenced the priorities of dissident groups. Religious differences can be seen in Lithuania too, where Catholic Church was very popular and become the staging point of dissent as well as for example creation of underground media such as Chronicle of Catholic Church in Lithuania, one of the most influential pieces of samizdat in whole Soviet Union. Churches in Latvia and Estonia, whether it would be Lutheran or Catholic did not enjoy such popularity thus their influence was highly marginal. This thesis does not compare only religious and national differences but also various other sociological and demographic...
