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. Graphene: Applications in Surface Science Studies
Abstract : This thesis addresses how graphene can be a valuable asset for surface science studies. Using a combination of X- ray photoelectron spectroscopy, scanning tunneling microscopy, and low-energy electron diffraction, we take advantage of graphene’s sensitivity to changes in its chemical environment to obtain an atomic scale understanding of different reactions occurring above and below the film.

3. Oxidation and Reconstructions of Alloy Model Catalysts : Platinum-Rhodium and Palladium-Gold
Abstract : Alloys and bimetallic systems have shown many advantages in heterogeneous catalysis, but the details of their catalytic functions are not always known. For instance, the atomic details about surface reconstructions under catalytic reaction conditions, or which phases that are high-active or low-active. READ MORE

5. Industrial Alloys Studied by Surface Sensitive Techniques
Abstract : This thesis reports on surface studies of industrial materials whose importance for society manifests in the vast range of applications. In industrial materials alloying is performed in order to improve the parent material's physical and mechanical properties such as strength, corrosion and wear resistance, as well as high temperature performance in comparison to the pure metal.
