Abstract

4H-SiC rectifiers with dual metal planar (DMP) Schottky contacts have been fabricated with a main titanium and an annular nickel contact. Fabricated diodes display low reverse leakage currents and low forward barrier heights. The diodes exhibited a high on/off current ratio (at 1 V/ - 500 V) exceeding 5.108.
