Dr. Ruby Ghosh: Silicon Carbide Research

The wide bandgap semiconductor silicon carbide (SiC) is a fascinating material. In the single crystal form it is an indirect gap semiconductor with 2.38 < E g < 3.26 eV (depending on polytype), which allows for electronic device operation to ~900 ° C. It is corrosion resistant to most acids and bases, and has a hardness of 9 (Mohs scale).
