  1. 1. Growth, structure and properties of ternary transition metal nitride thin films prepared by reactive magnetron sputtering

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

    Sammanfattning : Early transition metal nitrides have found an extensive use in a range of applications. Even though the use is wide there are still large fields to explore. The work in this thesis has been directed towards increasing the fundamental understanding of the synthesis, characterization, and properties for some technologically relevant nitrides. LÄS MER

  3. 2. 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

  4. 3. Fundamental aspects of HiPIMS under industrial conditions

    Författare :Mattias Samuelsson; Ulf Helmersson; Torbjörn Joelsson; Hans Högberg; Bengt Wälivaara; Jörg Patscheider; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : Fundamental aspects of the high power impulse magnetron sputtering (HiPIMS) process and its implication for film growth under industrial conditions have been studied. The emerging HiPIMS technique exhibits a higher plasma density and an enhanced degree of ionisation of sputtered material as compared to conventional direct current magnetron sputtering (DCMS).

  5. 4. High power impulse magnetron sputtering under industrial conditions

    Författare :Mattias Samuelsson; Ulf Helmersson; Torbjörn Joelsson; Hans Högberg; Bengt Wälivaara; Tomáš Kubart; Linköpings universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP;

    Sammanfattning : In this thesis, the recent development step of magnetron sputtering, termed high power impulse magnetron sputtering (HiPIMS) has been studied. Compared to conventional magnetron sputtering HiPIMS provides a higher plasma density which can ionise the sputtered material. LÄS MER
