Design of the atomic source producing carbon beams for deposition of graphene in UHV conditions
Horáček, Matěj ; Kolíbal, Miroslav (referee) ; Mach, Jindřich (advisor)
This bachelor's thesis deals with the design of the atomic source of carbon beams for deposition of graphene in UHV conditions. In the first part, problems on the growth of ultrathin layers, the theory of atomic beams and molecular beam epitaxy are described. The second part is aimed to graphene layers - especially the growth of graphene using molecular beam epitaxy. In the third part, the detection of carbon atomic beams is discussed. The practical part of this bachelor's thesis deals with the design and the construction of high-temperature atomic source of carbon. In the conclusion the obtained results are discussed.

Preparation of SiN ultrathin films
Dvořák, Martin ; Voborný, Stanislav (referee) ; Mach, Jindřich (advisor)
This bachelor´s thesis deals with design, testing and calibration of an effussion cell generating silicon atomic beam having thermal energy (0,1 - 1 eV). These beams are used for the preparation of Si and SiN ultrathin films. Silicon nitride and its applications in semiconductor industry are reviewed. First experiments with deposition of ultrathin films of Si and SiN are described. These layers have been analyzed by x-ray photoelectron spektroscopy (XPS) and atomic force microscopy (AFM).
