  1. 1. Plasma characterisation in high power pulsed magnetron sputtering

    Författare :Jones Alami; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : In this thesis, plasma parameters including plasma and floating potentials, electron energy distribution function (EEDF) plasma density and electron temperature are studied in a high power pulsed magnetron (HPPM) discharge at different Argon (Ar) gas pressures and different magnetron powers. It is reported that the EEDF during and shortly after the pulse can be represented by a bi-Maxwellian distribution indicating two energy groups of electrons. LÄS MER

  3. 2. Plasma Characterization & Thin Film Growth and Analysis in Highly Ionized Magnetron Sputtering

    Författare :Jones Alami; Ulf Helmersson; James Bradley; Linköpings universitet; []
    Nyckelord :Highly ionized pulsed magnetron sputtering; HPPMS; HPPIMS; thin film; plasma analysis; Langmuir probe; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : The present thesis addresses two research areas related to film growth in a highly ionized magnetron sputtering system: plasma characterization, and thin film growth and analysis. The deposition technique used is called high power pulsed magnetron sputtering (HPPMS). LÄS MER

  4. 3. Thin Film Growth using Pulsed and Highly Ionized Vapor Fluxes

    Författare :Viktor Elofsson; Kostas Sarakinos; Jones Alami; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : Microstructure and morphology of thin films are decisive for many of their resulting properties. To be able to tailor these properties, and thus the film functionality, a fundamental understanding of thin film growth needs to be acquired. LÄS MER

  5. 4. Nonstoichiometric Multicomponent Nitride Thin Films

    Författare :Rui Shu; Per Eklund; Arnaud Le Febvrier; Jones Alami; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : High entropy ceramics have rapidly developed as a class of materials based on high entropy alloys; the latter being materials that contain five or more elements in near-equal proportions. Their unconventional compositions and chemical structures hold promise for achieving unprecedented combinations of mechanical, electrical and chemical properties. LÄS MER
