  2. 1. Contacts on Silicon Carbide by Use of Nickel and Tantalum ---Preparation and Characterisation

    Author : Yu Cao; Chalmers tekniska högskola; []
    Keywords : Keywords: Silicon Carbide; Metal Contact; Thin Films; Preferential Etching; Interfacial Reaction; effect; Nickel; Tantalum; #955; Depth Profile; I-V Characteristics.;

    Abstract : Silicon carbide (SiC) is one of the attractive semiconductors due to its good electrical, thermal and mechanical properties. It is a promising material for high temperature, high power and high frequency application. Reliable electrodes are always necessary to utilise SiC for electronic devices. READ MORE

  4. 2. Thermally stable electrical contacts to 6H silicon carbide

    Author : Nils Lundberg; Mikael Östling; Claude Jaussaud; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; I-V current -voltage ; C-V capacitance-voltage ; rectifying; ohmic; interface; silicide; carbide; epilayer; Schottky barrier height; current rectification ratio CRR ; specific contact resistivity; transmission line model TLM ; contact resistance; transfer length; Electrical Engineering; Elektro- och systemteknik;

    Abstract : Silicon Carbide (SiC) are at present being developed for use in high temperature (≥ 500◦C) and high-power environments under which conventional semiconductors can hardly perform.  Thermally stable electrical contacts are essential to the ability of SiC to function under such extreme conditions.

    Abstract : Nanotechnology, the science of manipulating materials on an atomic or molecular scale is one of the fastest growing areas of research and technology. Nanotechnology has a vast range of applications in medicine, electronics, biomaterials and energy production. New developments in nanotechnology are growing all the time. READ MORE

  7. 5. Suicide attempt and genes : psychiatric and genetic characteristics of suicide attempters

    Author : Maj-Liz Persson; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Suicide; Attempted; Mental disorders; Association; Genetic markers; Serotonin; Norepinephrine; Dopamine;

    Abstract : Suicide affects an appreciable number of people in all societies. Finding genes that predispose to suicidal behavior may help to identify individuals at risk and an appropriate counseling and support can be extended to them. The studies of the present thesis focus on suicide attempt. READ MORE
