1. InP/GaInP Nanowires for Tandem Junction Solar Cells : Growth, Processing, and Characterization
Sammanfattning : Semiconductor nanowire solar cells have achieved comparable efficiency to their planar counterparts with substantial reduction of material consumption. Tandem geometry is a path towards even higher efficiency. However, extensive studies are needed to reach this goal. LÄS MER
2. Mechanosensing Using GaInP Nanowires
Sammanfattning : Mechanical forces exists in many cellular processes, including cell proliferation, migration, rearrangement and differentiation. The transformation of cancer cells from normal cells, cancer metastasis and cell rearrangement during morphogenesis all involve changes in cellular mechanical forces. LÄS MER
3. Scanning Tunneling Microscopy Induced Luminescence Studies of Semiconductor Nanostructures
Sammanfattning : This thesis treats scanning tunneling luminescence (STL) investigations of semiconductor nanostructures. The STL technique combines scanning tunneling microscopy (STM) with detection of photons, induced by the tunneling electrons. The high spatial resolution in STM and the local excitation allow for optical investigations on the nanometer-scale. LÄS MER
