1. Calculations of Clean and Adsorbate Covered Metal Surfaces and their Core-Level Photoemission Spectra
Sammanfattning : The present thesis is concerned with the theoretical study of x-ray photoemission spectra from clean and adsorbate-covered metal surfaces. The main tool is ab initio density functional (DFT) total energy calculations. LÄS MER
2. Adsorption of Molecules on Metal Surfaces Studied by High Resolution Core Level Photoemission
Sammanfattning : Various aspects of the adsorption of molecules on metal surfaces have been studied making use of different properties of high resolution core level photoemission. A thorough investigation has been performed of the ordering and the site occupancy of CO overlayers on Rh(111). CO has been shown to adsorb in on-top and three-fold-hollow sites. LÄS MER
3. Molecular overlayers on homogeneous and heterogeneous metal surfaces studied by core-level photoemission
Sammanfattning : The main topic of this thesis is the investigation of small molecules adsorbed on metal surfaces by means of core-level photoemission spectroscopy. The thesis consists of three parts; The first group of papers concerns the effects of internal molecular vibrations on the core-level photoemission spectra. LÄS MER
4. Electronic Structure of Some Zincblende Semiconductor Surfaces
Sammanfattning : The main aim of this thesis is to study and understand the surface electronic structure of compound semiconductors (ex. GaAs, InP, ..etc. LÄS MER
5. Core Level Spectroscopy of Water and Ice
Sammanfattning : A core level spectroscopy study of ice and water is presented in this thesis. Combining a number of experiments and spectrum calculations based on density functional theory, changes in the local valence electronic structure are shown to be sensitive to the local H-bonding configurations.
