11. Optical Characterization of III-Nitride and II-V Semiconductor Nanowires
Abstract : The optical properties of III-V semiconductor nanowires for optical devices have been investigated by photoluminescence spectroscopy, cathodoluminescence spectroscopy and cathodoluminescence imaging. The material systems that have been studied include the nitrides (InN, GaN and AlN) and ternaries, and a few common phosphides and arsenides. READ MORE

12. Doping of Semiconductor Nanowires
Abstract : In this thesis, in situ doping during growth of III-V semiconductor nanowires, primarily for photovoltaic applications, is investigated. The nanowires were grown by metalorganic vapor phase epitaxy (MOVPE), with gold seed particles. READ MORE

13. Optical spectroscopy of InGaAs quantum dots
Abstract : The work presented in this thesis deals with optical studies of semiconductor quantum dots (QDs) in the InGaAs material system. It is shown that for self-assembled InAs QDs, the interaction with the surrounding GaAs barrier and the InAs wetting layer (WL) in particular, has a very large impact on their optical properties.
