Photoluminiscence study of thin layers of MoS2
Kuba, Jakub ; Kunc,, Jan (referee) ; Bartoš, Miroslav (advisor)
The thesis deals with study of thin layers of transition metal dichalcogenides, especially of molybdenum disulfide. Nanostructures were fabricated on two-dimensional crystals of MoS2 and WSe2. Within followed analysis attention was paid to the photoluminescence properties. In the thesis transition metal dichalcogenides are reviewed and description of the modified process of preparation by micromechanical exfoliation is given.

Preparation of 2D heterostructures
Ředina, Dalibor ; Hrabovský, Miloš (referee) ; Bartoš, Miroslav (advisor)
This bachelor's thesis refers about preparation of 2D hetestructures here at the IPE, BUT. The first theoretical part deals with properties of graphene, molybdenum disulfide and 2D heterostructures in general. Comprehensive overview is provided by basic facts about properties and allotropic modifications of carbon. Next part of this thesis outlines methods used in the fabrication of heterostructures and highlights presumably the best one. Experimental part deals with optimization of this method. Successive steps of this method are improved by various adjustments in order to achieve the highest success rate in the fabrication of these heterostructures. Result of this approach is stated in this thesis.
