1. High-Aspect Ratio Nanofabrication for Hard X-Ray Zone Plates
Abstract : Hard x-ray nanoimaging enables structural investigations of new materials for many applications. For high-resolution experiments, zone plate x-ray optics are commonly chosen.Two methods of zone plate nanofabrication are presented in this thesis.Zone plates are circular diffraction gratings with radially decreasing grating period.

2. Fabrication and Charaterisation of Photonic Integrated Circuits
Abstract : The past few decades have seen an explosive increase ininformation transfer, fuelled by the enormous growth of theInternet, telecommunication applications, and mass mediasystems in general. Because of the very high bandwidthpotential promised by optical fibre communication technology,the area of all-optical networking has received a great amountof attention. READ MORE

3. High-Resolution Nanostructuring for Soft X-Ray Zone-Plate Optics
Abstract : Diffractive zone-plate lenses are widely used as optics in high-resolution x-ray microscopes. The achievable resolution in such microscopes is presently not limited by the x-ray wavelength but by limitations in zone-plate nanofabrication. READ MORE

4. Nanofabrication of Zone Plate Optics for Compact Soft X-Ray Microscopy
Abstract : This Thesis describes the development of the KTH/Stockholm nanofabrication process for diffractive soft x-ray optics. The effort is motivated by the need for and requirement of specially designed diffractive optics and test objects for compact x-ray microscopy as well as optics for other applications such as phase imaging.

5. Processing and characterization of GaN/SiC heterojunctions and SiC bipolar transistors
Abstract : Silicon Carbide (SiC) and Gallium Nitride (GaN) are bothwide bandgap semiconductors that have been suggested for highpower, high voltage, and high temperature applications. Themost investigated SiC devices so far are the Schottky diode,PiN diode and the field effect transistor. READ MORE
