11. Rosetta Langmuir probe performance
University essay from Institutionen för fysik och astronomiAbstract : Several Langmuir probe voltage sweeps by a model of the ESA spacecraft Rosetta was simulated in a plasma with solar wind parameters using the ESA open source software SPIS 5. The simulations were carried out to in- vestigate the features of the spacecraft’s environment in the solar wind and the effect of photoemission from the spacecraft surface on the measurements made by the Langmuir probes on board Rosetta.

12. Photoemission on the Rosetta spacecraft
University essay from Institutet för rymdfysik, UppsalaavdelningenAbstract : Rosetta is a European spacecraft that will rendevouz with andfollow the comet 67P/Churyumov-Gerasimenko from 2014 to 2015. Among other instruments are two Langmuir probes that measure certain plasma parameters. This study aims to describe the photoemssionon Rosetta and in particular on the Langmuir probes. READ MORE

13. Optical components of XUV monochromator : For use in laser based angle-resolved photoemission spectroscopy
University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)Abstract : At the division of Material Physics at KTH an angle resolved photoemission spectrometer (ARPES) is being built. This system uses a pulsed laser to create ultraviolet light through higher harmonic generation. The laser has a high output effect which puts the optical components of the system under a large heat load. READ MORE

14. Scanning Tunneling Microscopy and Low-Energy Electron Diffraction Studies of Quantum Wires on Si(332)
University essay from Karlstads universitet/Fakulteten för teknik- och naturvetenskapAbstract : In this master thesis I have investigated one-dimensional nanostructures, so called quantum wires. The goal was to grow them in situ on a stepped silicon surface and thereafter do several kinds of measurements, like Scanning Tunneling Microscopy, Low-Energy Electron Diffraction and Photoemission.

15. Ab-initio study of disorder broadening of core photoemission spectra in random metallic alloys
University essay from Institutionen för fysik, kemi och biologiAbstract : Ab-initio results of the core-level shift and the distribution about the average for the 3d5/2 electrons of Ag, Pd and 2p3/2 of Cu are presented for the face-centered-cubic AgPd and CuPd random alloys. The complete screening model, which includes both initial and final states effects in the same scheme, has been used in the investigations. READ MORE
