Semiconductor nanowire growth utilizing alloyed catalyst
Musálek, Tomáš ; Rezek, Bohuslav (referee) ; Kolíbal, Miroslav (advisor)
This master's thesis deals with growth of germanium nanowires using different catalyst particles. The emphasis is mainly layed on fabrication of specific alloyed catalyst consisting of (AgGa). In the first part of the thesis are mentioned two most common concepts of nanowire growth and the importance of phase diagrams for their interpretation. Method for production of alloyed catalyst is demonstrated and experiments focused on the growth of germanium nanowires using this catalyst were performed. Moreover, method for modification of germanium surface via anisotropic etching is demonstrated as well. Such etched structures are suitable for nanowire growth with the help of different kinds of catalyst particles or for the growth of nanowires made of various materials.
