11. Reshaping the phase diagram of YBa2Cu3O7-δ through strain in ultrathin films and nanowires
Abstract : This thesis aims at adding important pieces to the puzzle of understanding the physics of the High critical Temperature Superconductor (HTS) cuprates, where despite over 30 years of intense research many open questions remain. The HTS cuprates are characterized by an incredibly complex phase diagram with multiple intertwined local orders, such as charge density waves (CDW). READ MORE

12. Protective and Nanoporous Alumina Films Studied in situ by X-ray and Electrochemical Methods
Abstract : In this thesis, the studies of native and anodic oxides on both aluminum model single crystal surfaces as well as on aluminum alloys found in applications are presented. The focus has been on the characterization in situ as the oxide is growing by an electrochemical process called anodization. READ MORE

14. Fabrication of inverse opal oxide structures for efficient light harvesting
Abstract : Artificial opals are self-assembled face centered cubic (fcc) structures of spherically shaped beads, which interesting applications as photonic band gap materials. Inverse opals are photonic crystals consisting of fcc paced voids of a low refractive index material imbedded in a high refractive index material. READ MORE

15. Growth and Characterization of ZnO Nanocrystals
Abstract : The understanding of surfaces of materials is of crucial importance to all of us. Considering nanocrystals (NCs), that have a large surface to bulk ratio, the surfaces become even more important. Therefore, it is important to understand the fundamental surface properties in order to use NCs efficiently in applications. READ MORE
