  2. 1. Schottky Contacs on Silicon Nanowires

    Author : Johan Piscator; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Silicon On Insulator SOI ; Schottky contacts; Palladium silicide; Silicon nanowire;

    Abstract : This thesis demonstrates the effect of charge on Schottky barrier height for metal contacts at the end surfaces of silicon nanowires. It is shown, by measurements and analytical models, how the effective electron barrier is lowered by a positive charge introduced into an oxide embedding the wire. READ MORE

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

    Author : S. A. Perez-Garcia; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; interfacial reaction; metallic contacts; Silicon carbide; silicides; XPS.;

    Abstract : 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. READ MORE

  7. 5. Processing and characterization of silicon carbide (6H-SiC and 4H-SiC) contacts for high power and high temperature device applications
