2. Electronic materials : growth and characterisation
Abstract : In this thesis the InSb(111), InAs(111) and GaSb(001) surfaces have been studied by means of time- and angle-resolved photoemission spectroscopy based upon the femtosecond laser system. The pump-and-probe technique allows to analyse both electron states in the valence band and normally unpopulated electron states above the valence band, which can be occupied by transiently excited carriers at the optically pumped surface.

4. Vacuum Ultraviolet Scanning Photoelectron Microscopy, Instrumentation & Applications
Abstract : 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. READ MORE

5. Free Clusters Studied by Synchrotron-Based X-ray Spectroscopy: From Rare Gases to Metals
Abstract : The main topic of this Thesis is the x-ray spectroscopic studies of free nano-clusters with size more than 10^3 atoms. The photoelectron spectroscopy experiments on rare gas and metal clusters were performed at beamline I411 at MAX-lab National Swedish synchrotron radiation facility. Free rare-gas clusters are simplest objects in cluster research. READ MORE
