1. Epitaxial growth of semiconductor nanowires
Abstract : This thesis describes the results obtained from investigations carried out on epitaxially grown III-V semiconductor nanowires aimed at improving our understanding of and knowledge on the growth mechanism of nanowires. This is important to be able to control their growth, in order to make future applications possible. READ MORE

2. Transmission Electron Microscopy of III-V Nanowires and Nanotrees
Abstract : In this work, the morphology and crystal structure of epitaxial semiconductor nanowire structures grown by metal-organic vapour phase epitaxy (MOVPE) are studied by electron microscopy methods. In particular, the three-dimensional structure of nanowires and nanotrees has been characterised by scanning electron microscopy (SEM), high-resolution transmission electron microscopy (HRTEM) and multi-slice (MS) simulations.

3. Theoretical study of electronic structure and optical properties of semiconductor nanostructures
Abstract : In this thesis, the electronic structure and optical properties of semiconductor nanostructures are studied theoretically. Three types of nanostructures have been studied, silicon nanocrystals, free-standing III-V nanowires and free-standing GaAs/AlGaAs nanowire superlattices. READ MORE
