Use of biomaterials for optoelectronic applications in semiconductor technology
Čuboň, Tomáš ; Salyk, Ota (referee) ; Zmeškal, Oldřich (advisor)
The bachelor´s thesis is aimed to measurement optical properties of thin layer films of biomaterials which could be used in optoelectronics and semiconductor technology. DNA and BSA were chosen in order to represent such extensive group of biomaterials. The theoretical part describes the way of preparation of thin layer. It also provides some information about basic phenomena and biomaterials. The practical part is focused on the description of preparation of thin layer film using spin-coating method. The chosen materials were studied by optical microscopy, UV-VIS spectrophotometry and spectroscopic ellipsometry. The thickness of prepared samples was measured by mechanic profilometry. In the last section of the bachelor´s thesis, there is discussion and evaluation of results.

Study of optical properties of thin films of organic photovoltaic cells
Čuboň, Tomáš ; Schmiedová, Veronika (referee) ; Zmeškal, Oldřich (advisor)
This master´s thesis is focused on measurement of optical properties of thin layer of materials used in organic solar cells (OSC). The usage of graphene oxides and its reduced forms as parts of hole transport layer (HLT) in OSC were studied. At the beginning of the thesis, there is described basic theory necessary to understand the optical properties of thin layers. The thin layer deposition and reduction of GO are discussed too. The experimental part is aimed to the optical characterization of prepared thin films. The results from optical microscopy, UV-VIS spectroscopy, FT-IR spectroscopy and spectroscopic ellipsometry were obtained. At the end of the thesis, the results are concluded and compared with already published literature.
