1. Synthesis and In Situ ToF-LEIS Analysis of Ultrathin Silicides and Ti-based Films
Abstract : Thin films and coatings play a significant role in today’s society, with applications in electronics, optics, mechanics, and biomedicine. Further advancement in the field of surface coatings requires a good understanding of the unique features of ultrathin films and surfaces, which can only be reached with analysis techniques capable of resolving composition and morphology on a sub-nm scale.

2. 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

4. Titania Nanoscale Films and Surfaces : Surface Science Investigation of Structure and Properties
Abstract : This thesis presents surface science studies, investigating several aspects of titanium dioxide at the atomic scale. The greater part of this work is devoted to the preparation by chemical vapor deposition (CVD) of titanium(IV) tetraisopropoxide (TTIP) of ultrathin TiO2 or TiOx films on Au(111). READ MORE

5. YBCO nanowires to study nanoscale ordering in High-Tc Superconductors
Abstract : We present the realization of YBa2Cu3O7-δ (YBCO) nanowires for both basic physics studies, which could help to elucidate the microscopic mechanisms of High critical Temperature Superconductors (HTS), and for novel applications.The first part of the thesis describes an improved nanopatterning procedure, based on e-beam lithography in combination with an amorphous carbon mask and a very gentle Ar+ ion etching.
