1. Design and applications of an aperture-type near-field scanning optical microscope
Sammanfattning : .... LÄS MER
2. Optical Imaging and Spectroscopy of Metal Nanostructures
Sammanfattning : Noble metal structures with size in the sub 100 nm range exhibit extraordinary optical properties due to collective oscillations of conduction electrons, the surface plasmon resonances (SPR). The most remarkable feature of these structures is the ability to redistribute electromagnetic radiation and concentrate strong fields near the surface. LÄS MER
3. Near-field scanning optical microscopy and fractal characterization with atomic force microscopy and other methods
Sammanfattning : This thesis is devoted to the development of near-field scanning optical microscopy (NSOM) for aqueous solutions and to fractal characterization of steel surfaces with atomic force microscopy (AFM) and other methods. NSOM combines optical properties from a light microscope and the technique of scanning probe microscopy, SPM (invented in the early 1980’s). LÄS MER
4. Impact of carrier localization on recombination in InGaN quantum wells with nonbasal crystallographic orientations
Sammanfattning : The modern InGaN technology demonstrates high efficiencies only in the blue spectral region and low current operation modes. The growth of InGaN quantum wells (QWs) on nonbasal crystallographic planes (NBP) has potential to deliver high-power blue and green light emitting diodes and lasers. LÄS MER
5. Optical properties and degradation of deep ultraviolet AIGaN-based light-emitting diodes
