1. 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.

2. Electronic states of adsorbates and insulating overlayers on metal surfaces
Abstract : Electronic states of adsorbates and insulating overlayers provide a wealth of scientifically interesting phenomena with great technological importance. Interesting phenomena arise, for example, from the interaction of electronic states of an adsorbate with the continuum of metal electron states, both propagating bulk states and surface states.

3. Reactivity of Transition-Metal Compounds from Electronic Structure
Abstract : Transition-metal carbides (TMC's), nitrides, and sulfides belong to the class of materials known as transition-metal compounds (TMX's). Besides having intriguing properties, these materials are relevant for, e.g., growth and catalysis. READ MORE

4. Influence of Electron Charge States in Nanoelectronic Building Blocks
Abstract : The continued efforts to improve performance and decrease size of semiconductor logic devices are facing serious challenges. In order to further develop one of the most important nanoelectronic building blocks, the metal-oxide-semiconductor field-effect-transistor (MOSFET), several major problems have to be solved.
