1. Silicon δ-doping and Isoelectronic Doping in GaAs ans GaN Layers Grown by MBE
Abstract : This work concerns MBE-grown material, particularly physical effects due to controlled impurities of Si and N in arsenides, and the growth of nitrides and studies of Al- and As-impurities in them. Apart from interesting physical phenomena there are important device applications. The first part is devoted to studies of Si .delta. READ MORE

2. Photoelectron Spectroscopy Studies of III-V Semiconductor Systems
Abstract : Photoelectron spectroscopy has been used as a main tool to study a number of III-V semiconductor surfaces. This thesis includes studies of a surface reaction, As/InP(110), thin heteroepitaxial layers, InAs on GaAs(111)A and GaAs on AlAs(100), and a diluted magnetic semiconductor, Ga1-xMnxAs. READ MORE

3. Detailed photoemission studies of the prototype diluted magnetic semiconductor (Ga,Mn)As
Abstract : Magnetic semiconductors are materials that combine the key features needed in information technology, namely magnetism and controllable charge transport. The prospects of integrating these properties and of using the spin as informa-tion carrier have motivated large efforts to produce such materials for imple-mentation in future spin-based electronics.

4. Growth of ZnO/GaN distributed Bragg reflectors by plasma-assisted molecular beam epitaxy
Abstract : This thesis describes epitaxial growth of ZnO/GaN distributed Bragg reflectors by hybrid plasma-assisted molecular beam epitaxy on GaN(0001). The unique hybrid approach employed the same growth chamber for continuous growth of both ZnO and GaN without exposing the layers to the ambient conditions. READ MORE
