1. Spectroscopic studies of III-V semiconductors in two, one and zero dimensions
Abstract : In this thesis, spectroscopic studies of quantum wells (QWs), quantum wires (QWRs) and quantum dots (QDs) in III-V semiconductors are presented. The electronic structure of these low-dimensional structures have been studied by absorption, photocurrent, electroreflectance, photoluminescence (PL), and photoluminescence excitation (PLE) spectroscopy.

2. Cathodoluminescence Studies of Quantum Structures and III-V nitrides
Abstract : Characterization of low-dimensional semiconductor structures is a challenging task. The thesis is based on experiments, using cathodoluminescence (CL) as a tool for characterization. The high spatial resolution and the possibility of spectroscopy of small structures make CL one of the most powerful techniques for these types of investigations. READ MORE

3. Molecular mechanisms of HLA associations with myasthenia gravis
Abstract : Myasthenia gravis (MG) is a neuromuscular disease characterised by muscle weakness due to an autoimmune attack against the nicotinic acetylcholine receptor (nAChR). MG has a complex pattern of inheritance and several genetic and environmental factors are important in conferring susceptibility to the disease. READ MORE

4. On the influence of micro-and macroscopic surface modifications on bone integration of titanium implants
Abstract : Background: Osseointegrated titanium implants are routinely used in clinical denstistry as anchorage units for dental prostheses. Although the overall clinical results are good, there are clinical situations when an optimized implant healing is desirable, for instance in order to shorten healing periods and to allow immediate loading.

5. Characterization of Surfaces Relevant to Nanotechnology
Abstract : In this thesis investigations of the structure and dynamics of semiconductor surfaces relevant for the synthesis of nanostructures are presented. The studies were performed using Scanning Tunneling Microscopy (STM), Low Energy Electron Diffraction (LEED), and Spectroscopic PhotoEmission and Low Energy Electron Microcopy (SPELEEM). READ MORE
