1. Defects and Impurities in CdTe : An ab Initio Study
Sammanfattning : In this thesis defects and impurities in CdTe have been studied with ab initio methods. CdTe is a II-VI semiconductor with many important applications such as γ- and X-ray detectors, solar cells and medical imaging. LÄS MER
2. Development of methods for in situ measurements of radioactivity in the enviroment
Sammanfattning : In case of a release of radioactive nuclides into the environment it is necessary to have reliable methods to estimate the potential effect on population and ecosystem. In this context the total activity deposited, the elemental composition and its depth distribution are of importance. LÄS MER
3. Photochemical and Photoelectric Applications of II-VI Semiconductor Nanomaterials
Sammanfattning : In this work we investigated fabrication of semiconductor nanomaterials and evaluated their potential for photo-chemical and photovoltaic applications. We investigated two different II-VI semiconductor nanomaterial systems; (i) ZnO oriented nanowire arrays non-epitaxially grown from a substrate; and (ii) colloidal CdTe nanotetrapods synthesized by solution-based thermal decomposition of organo-metallic precursors.

4. In situ measurements of radionuclide concentration in soil : An investigation into detector properties and methods
Sammanfattning : In case of a release of radioactive nuclides into the environment it is necessary to have reliable methods to estimate the potential effect on people and the ecosystem. In this context the total activity deposited, the elemental composition and the depth distribution are of importance. LÄS MER
5. Electronic Structure of Some Zincblende Semiconductor Surfaces
Sammanfattning : The main aim of this thesis is to study and understand the surface electronic structure of compound semiconductors (ex. GaAs, InP, ..etc. LÄS MER
