1. Photoelectron Spectroscopy on HCl and DCl : Synchrotron Radiation Based Studies of Dissociation Dynamics
Sammanfattning : Dissociation dynamics of the ionized molecules HCl and the deuterated system DCl has been studied in gas-phase using synchrotron based photoelectron spectroscopy (PES).The inner-valence "(4σ)-1" photoionization band for DCl and HCl was recorded using maximum resolution in order to probe an interference pattern between a dissociative and a bound electronic state.

2. Photoelectron Spectroscopy of Cuprates and Manganites
Sammanfattning : Abstract In this thesis, the high temperature superconductors (HTSC) La2CuO4+x and Bi2Sr2CaCu2O8+d and the colossal magnetoresistive (CMR) La1-xSrxMnO3 have been studied by photoelectron spectroscopy. Techniques such as angular resolved photoemission (ARPES), resonant photoemission spectroscopy (RESPES) and x-ray absorption spectroscopy have been applied, using synchrotron radiation. LÄS MER
3. Vacuum Ultraviolet Scanning Photoelectron Microscopy, Instrumentation & Applications
Sammanfattning : This thesis describes the design and characterisation of a vacuum ultraviolet scanning photoelectron microscope as well as results from studies of laterally inhomogeneous surfaces. The instrument utilises synchrotron radiation from an undulator at the 550 MeV storage ring at the MAX-laboratory. LÄS MER
4. Photoelectron Spectroscopy Studies of III-V Semiconductor Systems
Sammanfattning : Photoelectron spectroscopy has been used as a main tool to study a number of III-V semiconductor surfaces. This thesis includes studies of a surface reaction, As/InP(110), thin heteroepitaxial layers, InAs on GaAs(111)A and GaAs on AlAs(100), and a diluted magnetic semiconductor, Ga1-xMnxAs. LÄS MER
