  1. 21. Growth and characterization of TiN/SiNx multilayer thin films

    Författare :Hans Söderberg; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering Materials; Materialteknik;

    Sammanfattning : The demands from industry for higher cutting speeds, feeding rates, and reduction of the use of cooling agents during turning and milling operations are increasing. Consequently the requirements on the cutting inserts are increasing and new advanced coatings that can withstand the higher temperatures and larger loads are highly sought after. LÄS MER

    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CZTS; thin film solar cells; back contacts; passivation; interface; titanium nitride; ATO; antimony-doped tin oxide; transparent back contact; CZTS; tunnfilmssolceller; bakkontakter; passivering; gränsskikt; mellanskikt; titannitrid; antimondopad tennoxid; ATO; transparent bakkontakt; Teknisk fysik med inriktning mot elektronik; Engineering Science with specialization in Electronics;

    Sammanfattning : In this thesis, alternative back contacts for Cu2ZnSnS4 (CZTS) thin film solar cells were investigated. Back contacts for two different configurations were studied, namely traditional single-junction cells with opaque back contacts and transparent back contacts for possible use in either tandem or bifacial solar cell configuration.

  4. 23. Investigation of Novel Metal Gate and High-κ Dielectric Materials for CMOS Technologies

    Författare :Jörgen Westlinder; Jörgen Olsson; Stefan Bengtsson; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electronics; metal gate; high-κ dielectics; titanium nitride; zirconium nitride; MOSFET; thin film; tantalum oxide; aluminum nitride; Elektronik; Electronics; Elektronik;

    Sammanfattning : The demands for faster, smaller, and less expensive electronic equipments are basically the driving forces for improving the speed and increasing the packing density of microelectronic components. Down-scaling of the devices is the principal method to realize these requests. LÄS MER

  5. 24. Study of Electrochemical Behaviour and Corrosion Resistance of Materials for Pacemaker Lead Applications
