  2. 1. Detection and removal of traps at the SiO2/SiC interface

    Author : Halldor Olafsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; interface states; thermally stimulated current TSC ; positron annihilation spectroscopy PAS ; silicon carbide SiC ; metal-oxide-semiconductor field-effect transistor MOSFET ; transmission electron microscopy TEM ; deep level transient spectroscopy DLTS ; metal-oxide-semiconductor MOS ; field-effect mobility; capacitance-voltage C-V ;

    Abstract : The interface between silicon dioxide (SiO2) and silicon carbide (SiC) is at the heart of the SiC metal-oxide-semiconductor field-effect (MOSFET) transistor. The technology to produce a high quality SiO2/SiC interface does not exist today, hampering further development of the SiC MOSFET. READ MORE
