Molecular Beam Epitaxial Growth of III-V Semiconductor Nanostructures on Silicon Substrates
(2013-07-24)
The main focus and concerns of this PhD thesis is the growth of III-V semiconductor nanostructures (Quantum dots (QDs) and quantum dashes) on silicon substrates using molecular beam epitaxy (MBE) technique. The investigation of influence of the major growth parameters on their basic properties (density, geometry, composition, size etc.) and the systematic haracterization of their structural and optical properties are the core of the research work. The monolithic integration of III-V optoelectronic devices with silicon ...

Development of UNCD-based multielectrode arrays for neuronal measurements
(2017-07-26)
The work in hand will show how some of diamond’s extraordinary features can be utilized in bio-applications especially for in vitro cultures of neuronal cells. Diamond has proven itself as an excellent material for bio-applications such as simple fluorescent microarrays over bioFET (field effect transistor) to bioMEMS (microelectro-mechanical systems). The reason does not only lie in its best known properties namely extreme hardness and high refractive index, but in its unique chemistry. As one of the modifications ...
