Preparation of contacts to one-dimensional nanostructures
Citterberg, Daniel ; Procházka, Pavel (referee) ; Kolíbal, Miroslav (advisor)
This bachelor thesis deals with methodology of contacting one-dimensional nanostructures. Theoretical part of the thesis defines the concept of one-dimensional nanostructures, then it deals with the potential of their usage, especially in field effect transistors. This part also deals with the possibility of measuring the electrical properties of one-dimensional nanostructures and the possibility of fabricating contacts with sufficiently small sizes using litographic approach. Experimental part gives a brief overview of the tasks that need to be done during the contact fabrication. Subsequently, the individual steps are described in more detail and, finally, initial results of electrical characterization are shown.

Integration of nanostructures into functional devices
Citterberg, Daniel ; Mikulík, Petr (referee) ; Kolíbal, Miroslav (advisor)
This master thesis is focused on characterization of electrical transport properties of one-dimensional nanostructures. First section of this work deals with theoretical description of the experimental approaches to realization of such measurements. This section involves also a detail discussion of preparation of contacts using e-beam lithography. Next, theoretical description of characterization of nanostructures using photoluminescence measurements is given. Second section describes practical application of the aforementioned electrical transport measurements. Presented results include transport and photoluminescence measurements of WS2 nanotubes, InAs and WO2.72 nanowires. The last section of this thesis deals with nanowire quantum well heterostructures. The section provides both a deeper theoretical view of the problem and results of the photoluminescence measurements are shown.
