Preparation of GeSn nanostructures
Jedlička, Jindřich ; Voborný, Stanislav (referee) ; Kolíbal, Miroslav (advisor)
This bachelor thesis deals with the methods of preparation of GeSn nanowires. In the theoretical part of the thesis the band structure of solid states is described and the interesting properties of GeSn material are mentioned. The growth mechanism of nanowires and methods of preparation of GeSn nanowires are introduced. In the experimental part of the thesis the effusion cell for Sn deposition was assembled and the testing and calibration were performed.

Growth of ZnO nanowires
Mikula, Martin ; Voborný, Stanislav (referee) ; Kolíbal, Miroslav (advisor)
In this thesis the most important properties of nanowires are briefly characterized and possible methods of their synthesis are described. Special attention is paid to zinc oxide nanostructures as well as VLS mechanism, which is crucial for explanation of nanowire growth. Furthermore, deposition chamber for growth of ZnO nanowires has been assembled and effusion cell for zinc has been tested. Testing of the cell revealed one major drawback of its design, which prevents its use for zinc deposition. Therefore, no growth of ZnO nanowires has been carried out and before it can be accomplished, the effusion cell has to be modified.
