21/6/2013· The predicted BFOM for silicon carbide of more than 1000 provided strong motivation for development of unipolar devices from the available 6H-SiC polytype material in the 1990s. The first high-voltage (400 V) SiC Schottky rectifier with low (~1 V) on-state voltage drop and excellent reverse recovery characteristics was reported by NCSU in 1992 [ 9 ].
