6. Microstructural properties of some oxide thin films studied by X-ray diffraction and extended X-ray absorption fine structure
Abstract : The microstructure of some high-temperature superconductorrelated oxide thin films was studied by X-ray Diffraction (XRD)and Extended X-ray Absorption Fine Structure (EXAFS)techniques. A general one-dimensional kinematic x-raydiffraction model was further developed to quantitativelyanalyze the structural properties of complex layered films. READ MORE

7. Energy Relevant Materials: Investigations Based on First Principles
Abstract : Energy production, storage and efficient usage are all crucial factors for environmentally sound and sustainable future technologies. One important question concerns the refrigeration industry, where the energy efficiency of the presently used technologies is at best 40% of the theoretical Carnot limit. READ MORE

9. Magnetooptical properties of dilute nitride nanowires
Abstract : Nanostructured III-V semiconductors have emerged as one of the most promising materials systems for future optoelectronic applications. While planar III-V compounds are already at the center of the ongoing lighting revolution, where older light sources are replaced by modern white light LEDs, fabricating such materials in novel architectures, such as nanowires and quantum dots, creates new possibilities for optoelectronic applications.

10. Micro-photoluminescence and micro-Raman spectroscopy of novel semiconductor nanostructures
Abstract : Low-dimensional semiconductor structures, such as one-dimensional nanowires (NWs) and zerodimensional quantum dots (QDs), are materials with novel fundamental physical properties and a great potential for a wide range of nanoscale device applications. Here, especially promising are direct bandgap II-VI and III-V compounds and related alloys with a broad selection of compositions and band structures. READ MORE
