  5. 4. Tailoring of Contacts on Silicon Carbide - Procedures and Mechanisms

    Författare :S. A. Perez-Garcia; Chalmers University of Technology; []
    Nyckelord :interfacial reaction; metallic contacts; Silicon carbide; silicides; XPS.;

    Sammanfattning : Silicon carbide (SiC) exhibits very good electrical, thermal, chemical and mechanical properties which make it suitable for the next generation of wide band gap electronic devices, where silicon (Si) cannot be used due to its limitations with respect to the mentioned properties. Nickel (Ni) and Tantalum (Ta) are among the metals used for the contact formation. LÄS MER
