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

    Author : Yu Cao; Chalmers University of Technology; []
    Keywords : Keywords: Silicon Carbide; Metal Contact; Thin Films; Preferential Etching; Interfacial Reaction; effect; Nickel; Tantalum; λ; 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. 4. Suicide attempt and genes : psychiatric and genetic characteristics of suicide attempters

    Author : Maj-Liz Persson; Karolinska Institutet; Karolinska Institutet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; 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 focuse on suicide attempt. READ MORE

  5. 5. Parity Effects in Single Charge Tunneling

    Author : Magnus Gisselfält; Chalmers University of Technology; []
    Keywords : mesoscopic; single charge tunneling; photon-assisted tunneling; shot noise; SET transistor; parity effect; Andreev tunneling; Coulomb blockade;

    Abstract : The subject of this thesis is single charge tunneling effects, especially parity effects, as they are manifested in quantum mechanical tunneling through a metallic island small enough to cause single electrons to block tunneling of other electrons due to Coulomb interaction. When the island is superconducting the ground state energy depends on the parity of the number of electrons on the island: outside of the condensate there will always be at least one electron contributing to the energy for an odd number of electrons and this will have observable consequences.
