1. Reaction Mechanisms and Dynamics in the Early Stage of High-κ Oxide Atomic Layer Deposition : Investigations by In Situ and Operando X-ray Photoemission Spectroscopy
Abstract : Atomic layer deposition (ALD) is an outstanding deposition technique to deposit highly conformal and uniform thin films with atomic precision. In particular, ALD of transition metal oxide layers from metal amido complexes and water finds its way in several technological fields, including green energy devices and in the semiconductor industry.

2. Chemical and electronic structure of electroluminescent materials and interfaces in polymer-LEDs
Abstract : Following the discovery that conjugated polymers can be used as the emitting layer in light emitting devices, extensive studies on these materials have been carried out. In a few years, due to the development of new materials and an increasing knowledge of the underlying chemistry and physics, the performance has improved a lot. READ MORE

3. Rare-gas Clusters Studied by Electron Spectroscopy : Structure of Heterogeneous Clusters and Effects of Electron Scattering on Auger Decay
Abstract : In this Thesis experimental studies of nano-clusters using synchrotron radiation based photoelectron (UPS and XPS) and Auger Electron Spectroscopy (AES) are presented. The investigations may be divided into two parts where the first reports on the structure of heterogeneous two component clusters, and the second concerns electronic decay processes. READ MORE

4. Development of new characterization techniques for III-V nanowire devices
Abstract : This dissertation presents the new methods and techniques developed to investigate the properties of nanowires (NWs) and NW devices and the results obtained using these methods. The growth and characterization of NWs have become a large research field because NWs have been shown to improve the properties of many semiconductor applications such as transistors, solar cells, and light emitting diodes.

5. Conjugated materials for organic electronic devices : photoelectron spectroscopy studies
Abstract : Conjugated materials have attracted great attention since the discovery of high conductivity in donor and acceptor doped polyacetylene over two decades ago. The discoveries mentioned below caused, however, that the interest begun to shift towards their pristine semi-conducting state. READ MORE
