Application of hollow core optical fibers for the production and modification of nanostructures
Dejmek, Michael ; Průša, Stanislav (referee) ; Spousta, Jiří (advisor)
This bachelor thesis deals with the development of a new generation of SPM probes, specifically the creation and modification of nanostructures in SEM. In the framework of the presented work, we describe the light guidance in standard optical fibers and the light and gas guidance through photonic crystal fibers. We also describe the methods used (electron beam induced deposition, chemical vapour deposition) for the creation of nanostructures. In the experimental part we discuss the design and subsequent testing of the setups used for the creation of nanostructures. The results show that our method is successful and thus offers a new possibility for the creation of nanostructures at the Institute of Physical Engineering, FME BUT.

The preparation of Grafen by method CVD
Procházka, Pavel ; Kromka,, Alexander (referee) ; Mach, Jindřich (advisor)
This diploma thesis is mainly focused on the fabrication of graphene layers on the copper foil by the Chemical Vapor Deposition (CVD). For this purpose the high-temperature chamber for the production of the graphene was completed and fully automated. The production of the high area graphene on the copper foil was experimentally achieved. The Raman microscopy and X-ray photoelectron spectroscopy measurements proved that the produced graphene is mostly a monolayer. Graphene layer was transferred on non-conductive substrate.
