Study of microdefects in Czochralski silicon
Španělová, Klára ; Cába, Vladislav (referee) ; Másilko, Jiří (advisor)
The bachelor's thesis deals with the study of microdefects in Czochralski silicon in cooperation with the company onsemi Rožnov pod Radhoštěm. The main objectiv is to find knowledge about microdefects in Czochralski silicon and their influence on the properties of semiconductor components. The experimental part deals with the characterization of microdefects in Czochralski silicon ingots doped by B, P and Sb and grown in the company onsemi. Specifically, the measurement of radial resistivity is performance using a four-point probe with subsequent conversion to dopant concentration (according to ASTM F 723-99). The radial and axial distribution of microdefects in Czochralski silicon ingots is evaluated using the precipitation test and the OISF test. The position of the vacant-interstitial interface was also detected as part of microdefect study.

New corporate design of Švandovo divadlo
Španělová, Klára ; Slanec, Jaroslav (advisor) ; Malý, Radek (referee)
The work focuses on a Corporate design that shapes the brand identity. The goal is to design and create a new Corporate design for the Švandovo Theatre. In the theoretical part, I describe the functions of graphic design in a general sense. Then, I focus on the Corporate design and explain why it is crucial for all brands in the context of communication. I also examine, how local theater institutions use graphic design. I delve deeper into theaters that have decided to completely change their visual identity and have undergone a redesign. Lastly, I analyze the current visual style of the Švandovo Theatre, searching for specific challenges and opportunities for change. Using the acquired knowledge, I present my original proposal for a new graphic solution. It includes the logo, its variations, a specific color palette, and typefaces. I further present the visual style on a series of four different posters that advertise Švandovo Theatre's performances. I complement it with the graphic design of the tickets, the program, and the theater's promotional items. The main output of the work is a graphic manual that also describes the inspiration and meaning of each decision made in creating the graphic solution.
