The topic of this dissertation is embedded into the new-born field of inorganic nanowires. The research was focused on zinc oxide (ZnO) nanowires, in particular, which besides posing fundamental questions in physics, promise broad range of applications. Zn ...
Doped catalyst-free GaAs nanowires have been grown by molecular beam epitaxy with the gallium-assisted method. The spatial dependence of the dopant concentration and resistivity have been measured by Raman spectroscopy and four point electrical measurement ...
The role of Fe as an acceptor and Nb as a donor in 0.94−xTiO3–0.06BaTiO3−x (K0.5Na0.5)NbO3 (100xKNN) (x = 0.02 and 0.03) lead-free piezoceramics was investigated. X-ray diffraction analyses show that all the profiles are best-fitted with a cu ...
The electrical properties of vertically aligned silicon nanowires doped by ion implantation are studied in this paper by a combination of electron beam-induced current imaging and two terminal current−voltage measurements. By varying the implantation param ...
Electrochemical replication of nanoporous membranes represents a facile approach towards the fabrication of nanostructures with tailored properties. By the template method we prepared multisegment nanowires with tailored structure. The first step of the pr ...
The a-Si:H / c-Si heterostructure, is an attractive solution to avoid the presence of highly recombinative metal contacts at the surfaces of c-Si based solar cells. To assure good interface passivation, insertion of a sandwiched thin device-grade intrinsic ...
The nature of the Verwey transition in magnetite (Fe3O4) remains an unsolved puzzle after more than 60 years. Impurities and dopants present in magnetite can alter the Verwey transition temperature T-v as well as other physical characteristics of magnetite ...
Gold, silver and copper defects in germanium are modeled using density functional theory. The structures and electrical properties of the substitutional metals are calculated in excellent agreement with experiment. Interstitial Au, Ag and Cu are found to b ...
Density-functional theory is used to model interstitial iron and its complexes with aluminum in Si-rich SiGe alloys with Ge concentration up to 8%. Both short-range and long-range defect-Ge interactions are considered. It is found that Fe prefers Si-rich r ...
In the context of the diminishing fossil energy resources and global warming, much research is focused on sustainable energy sources. The research that is presented in this thesis falls in this category as it contributes to the development of a device that ...
