Physical simulation, fabrication and characterization of high-voltage Ni/4H-SiC Schottky rectifiers are studied. We demonstrate a blocking voltage of 3.85 kV by utilizing a 43 mum thick low doped 4H-SiC epilayer in vertical hot-wall Chimney CVD reactor. A high breakdown voltage of 3.56 kV was achieved on a layer grown by conventional hot-wall CVD reactor. The reverse leakage current on CVD sample was as low as 5 x 10(-6) A cm(-2) at 3.5 kV just before the breakdown.
