  1. 21. Electronic Properties of Metal Oxide Films Studied by Core Level Spectroscopy

    Författare :Jan Hinnerk Richter; Anders Sandell; Håkan Rensmo; Anne Borg; Uppsala universitet; []
    Nyckelord :Physics; electron spectroscopy; metal oxide; chemical vapour deposition; ion insertion; metal organic; band alignment; zirconium; titanium; silicon; high k; Fysik;

    Sammanfattning : In this dissertation core level electron spectroscopy has been employed to study various aspects of metal oxide films grown under ultra-high vacuum conditions. Studies on in situ ion insertion of lithium into thin TiO2 systems were performed. LÄS MER

  3. 22. Transition metal carbide nanocomposite and amorphous thin films

    Författare :Olof Tengstrand; Lars Hultman; Per Eklund; Axel Flink; Allan Matthews; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : This thesis explores thin films of binary and ternary transition metal carbides, in the Nb-C, Ti-Si-C, Nb-Si-C, Zr-Si-C, and Nb-Ge-C systems. The electrical and mechanical properties of these systems are affected by their structure and here both nanocomposite and amorphous thin films are thus investigated. LÄS MER

  4. 23. Reshaping the phase diagram of YBa2Cu3O7-δ through strain in ultrathin films and nanowires

    Författare :Eric Wahlberg; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; phase-slip; strange metal; High-Tc superconductors; thin-films; underdoped; nanowires; YBCO; charge density wave;

    Sammanfattning : 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). LÄS MER

  5. 24. Nanostructural design of transition metal nitride thin films

    Författare :Torbjörn Joelsson; Ivan Petrov; Linköpings universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP;

    Sammanfattning : Early transition metal nitrides have found extensive use in a range of thin film applications. We are just beginning to understand their growth from vapor phase deposition and microstructure-property relationships. LÄS MER

  7. 25. Electronic and Structural Properties of Thin Films of Phthalocyanines and Titanium Dioxide
