  1. 1. Gas flow sputtering of Cu(In,Ga)Se2 with extra selenium supply

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Fasta tillståndets elektronik

    Nyckelord :Gas flow sputtering; CIGS; selenium; thin film; solar cell;

    Sammanfattning : In this thesis CIGS absorber layers have been deposited by gas flow sputtering with an extra supply of selenium, a method that displays promise for large scale production because of its one-step sputtering route which deposits low energy particles in a high deposition rate. In this thesis a method was developed where selenium was added to the sputtering process inside the sputter chamber in a controllable manner and in larger amount than done in previous projects.

  3. 2. The Functionalization of Epitaxial Graphene on SiC with Nanoparticles towards Biosensing Capabilities

    Master-uppsats, Linköpings universitet/Institutionen för fysik, kemi och biologi; Linköpings universitet/Tekniska fakulteten

    Författare :Carl Strandqvist; [2015]
    Nyckelord :Graphene; Epitaxial; Silicon carbide; SiC; Nanoparticles; NPs; TiO2; Fe3O4; Functionalization; Gas sensing; CO; CH2O; C6H6; NH3; Carbon monoxide; Formaldehyde; Benzene; Ammonia; WHO; Hollow cathode; plasma sputtering; AFM; XPS; Raman spectroscopy; Surface characterization; Surface potential; Biosensor; Biosensing;

    Sammanfattning : Graphene has been shown to be very powerful as a transducer in many biosensor applications due to its high sensitivity. This enables smaller surfaces and therefore less material consumption when producing sensors and concequently cheaper and more portable sensors compared to the commercially available sensors today.

  4. 3. Deposition of CIGS absorber layer by gas flow sputtering : Initiation of project

    Uppsats för yrkesexamina på avancerad nivå, Fasta tillståndets elektronik

    Författare :Anders Åsberg; [2013]
    Nyckelord :GFS; gas flow sputtering; CIGS;

    Sammanfattning : The photovoltaic solar cell industry is growing rapidly, but high cost per watt is still an obstacle. Thin film solar cells, especially thin film solar cells using CIGS absorbers that have the highest proven efficiency, have the potential to reduce the cost through cheap manufacturing. LÄS MER

  5. 4. Syntes och egenskapskarakterisering av volframoxid framställd med magnetronsputtring

    Uppsats för yrkesexamina på avancerad nivå, Institutionen för materialkemi

    Författare :Matilda Schander; [2011]
    Nyckelord :reaktiv magnetronsputtring; volframoxid; dekorativa beläggningar;

    Sammanfattning : The system tungsten-oxygen has potential of being suitable for decorative coatings since ceramic coatings are often hard and wear resistant, and since modulations in oxygen content or incorporation of small ions could give bright colours. The aim of this report was to investigate the relationship between process parameters and  the properties of the films, with the wear resistance being of special interest. LÄS MER
