2. Transmission Electron Microscopy of Semiconductor Nanowires
Abstract : Semiconductor nanowires are studied by using transmission electron microscopy (TEM) based methods in this work. In the first section, the growth mechanism of gallium arsenide nanowires grown by chemical beam epitaxy is investigated. The nanowires are epitaxially grown from a gallium arsenide substrate by using gold seed particles as catalysts. READ MORE

3. Thermal barrier coatings for diesel engines
Abstract : The upward trend in internal combustion engine efficiency is driven by the demands for emission reduction and fossil fuel depletion. No present alternative fuel can produce energy comparable to that produced by conventional oil; this necessitates the reasonable, efficient usage of oil. READ MORE

4. Oxidation of some Late Transition Metal Surfaces: Structural Studies from UHV to Atmospheric Pressure
Abstract : The oxidation of Rh, Pd and Pt is studied under conditions ranging from ultra high vacuum to ambient pressures, with emphasis on a complete understanding of the geometry of the various oxide structures found. The investigations use a combination of various experimental methods, including high resolution core level spectroscopy, low energy electron diffraction, surface x-ray diffraction and scanning tunneling microscopy, as well as density functional theory calculations.

5. 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
