Reduction of the power dissipation in silicon carbide

A dual-metal-planar rectifier on 6H-SiC was fabried using Ti and Ni 2 Si as Schottky metals. The forward current voltage (I-V) characteristic of the dual-metal devices was comparable with that of Ti diodes. On the other hand, under reverse bias, almost the same leakage current of the Ni 2 Si rectifiers was achieved, i.e., a factor 1000 lower than that of Ti diodes.
