  3. 27. Sputtered Carbon Nitride Thin Films

    Författare :Niklas Hellgren; Bernd Schultrich; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The relation between the growth conditions and the film structure and properties of reactively magnetron sputtered carbon nitride CNx (0 ≤ x ≤ 0.6) thin films has been studied. The growth of CNx films has been studied when varying the process parameters, such as substrate temperature, N2 (partial) pressure and ion flux. LÄS MER

    Författare :Mats P. Johansson; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : Growth, microstructure and mechanical properties of boron nitride: carbon (BN:C) have been studied in films prepared by reactive r.f. diode sputter deposition as well as by reactive unbalanced d.c. LÄS MER

  5. 29. Me-Si-C (Me= Nb, Ti or Zr) : Nanocomposite and Amorphous Thin Films

    Författare :Olof Tengstrand; Lars Hultman; Per Eklund; Benny André; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : This thesis investigates thin films of the transition metal carbide systems Ti-Si-C, Nb-Si-C, and Zr-Si-C, deposited at a low substrate temperature (350 °C) with dc magnetron sputtering in an Ar discharge. Both the electrical and mechanical properties of these systems are highly affected by their structure. LÄS MER

  7. 30. High resolution microstructural characterization of oxide thin films and interfaces

    Författare :Nikolina Tuzla; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; oxides; Microstructure; TEM; thin films; interfaces; HAADF STEM; YSZ.; SrTiO3; 2DEG; LaAlO3; heterostructures;

    Sammanfattning : Oxide interfaces can introduce properties that are different compared to thecorresponding crystal bulk properties. The properties can be tuned by changing thestructure. It has become clear that these oxide interface systems are potentiallysuitable for future electronic devices with unique and tailored properties. LÄS MER
