1. 1. HiPIMS-based Novel Deposition Processes for Thin Films

   Författare :Asim Aijaz; Ulf Helmersson; Kostas Sarakinos; Linköpings universitet; []
   Nyckelord :;

   Sammanfattning : In this research, high power impulse magnetron sputtering (HiPIMS) based new deposition processes are introduced to address; the issue of low degree of ionization of C in magnetron sputtering discharges, and the difficulty encountered in thin film deposition on complex-shaped surfaces. The issue of low degree of C ionization is addressed by introducing a new strategy which is based on promoting the electron impact ionization ofC by increasing the electron temperature in the plasma discharge using Ne, instead of conventionally used Ar.

3. 2. Synthesis of Carbon-based and Metal-Oxide Thin Films using High Power Impulse Magnetron Sputtering

   Författare :Asim Aijaz; Ulf Helmersson; Kostas Sarakinos; Günter Bräuer; Linköpings universitet; []
   Nyckelord :;

   Sammanfattning : The work presented in this thesis deals with synthesis of carbon-based as well as metal-oxide thin films using highly ionized plasmas. The principal deposition method employed was high power impulse magnetron sputtering (HiPIMS). LÄS MER
