1. Nanoscale Crystal Growth: The Importance of Interfaces and Phase Boundaries Kristallväxt på Nanometer Skala: Vikten av Ytor och Gränser
Abstract : Surfaces and interfaces have a special significance to nanotechnology because the surface/volume ratio of nanomaterials is larger than for bulk materials. Therefore, interfaces of nanomaterials are usually more important to the properties of nanomaterials than for larger scale materials. READ MORE

2. 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

3. Preparation and characterisation of refractory whiskers and selected alumina composites
Abstract : A whisker is a common name of single crystalline inorganic fibre of small dimensions, typically 0.5-1 μm in diameter and 20-50 μm in length. Whiskers are mainly used as reinforcement of ceramics. This work describes the synthesis and characterisation of new whisker types. READ MORE

4. Silicon nanowire based devices for More than Moore Applications
Abstract : Silicon nanowires (SiNW) are in the spotlight for a few years in the research community as a good candidate for biosensing applications. This is attributed to their small dimensions in nanometer scale that offers high sensitivity, label-free detection and at the same time utilizing small amount of sample. READ MORE

5. Carbothermal synthesis of transition metal carbide and carbonitride whiskers via a Vapour-Liquid-Solid (VLS) growth mechanism
Abstract : A route for the synthesis of TiC, TiCyN1-y, TaxTi1-xC and TaxTi1-xCyN1-y whiskers via a carbothermal Vapour-Liquid-Solid (VLS) growth mechanism, yielding 70-90 vol.% whiskers, has been established. The whiskers were uniform in diameter (0.3-0. READ MORE
