Preparation and characterization of MoS2 thin films
 Tomková, Renáta ; Zahradníček, Radim (referee) ; Bartoš, Miroslav (advisor)
This thesis deals with topological insulators, which are described by the quantum spin Hall effect, as well as on semiconductors, where the band structure of semiconductors and more specifically mentioned unipolar transistor MOSFET is explained. There are also mentioned primarily 2D materials and in particular of MoS2. Topic focuses on its structure, the electric properties, the use and preparation by using micromechanical exfoliation. In the last chapter it is described how to prepare MoS2 structures and their analysis. Structural properties of this material were measured by the AFM and Raman spectroscopy. The experimental part there are illustrative photograph of MoS2 taken with an optical microscope and spatial structures created by AFM.

Assessment of the influence of the specimen orientation on the transition temperature TSP determined using small punch test method
 Tomková, Renáta ; Pantělejev, Libor (referee) ; Válka, Libor (advisor)
The diploma thesis is aimed to assesment of the influence of the specimen orientation during the Small Punch Tests (SPT). Steel ČSN 41 0214, or its equivalent steel RFe80, W.-Nr. 1.104 was chosen for experiments. Resulting records from SPT were evaluated using already known correlations which are reported in literature. The correlation values were compared with values obtained by the standard tests like Charpy impact test and tensile test. The influence of axial, radial and tangential test specimens orientation is discussed in relation to Ductile-to-Brittle fracture behaviour of the steel.
