Applications for 6H-Silicon Carbide Devices

Abstract

A variety of devices with promising characteristics have recently been demonstrated that confirm the potential for 6H-SiC. There are four primary application areas for 6H-SiC devices: 1) optoelectronics, 2) high temperature electronics, 3) radiation hard electronics, and 4) high power/high frequency devices. Optoelectronic devices include blue light emitting diodes and UV photodiodes. High temperature devices cover almost any device in SiC, from pn junctions to FET-based integrated circuitry. Radiation hard and EMP hard 6H-SiC devices can greatly improve the survivability of military systems and enhance nuclear reactor electronics. High power and high frequency devices in 6H-SiC can increase the power density of solid state devices by at least a factor of four over what is currently available and can also increase the operating temperature of these devices.
