Cree

I found this interesting....a slightly less technical description of the uses of SiC (besides LED's). This is from the Siemens website and is probably pretty old but I still found it informative (will probably be less so for those who know the Cree story well). Here's an excerpt....

w1.siemens.de

Short-circuit! The desk light silently goes off and the office is plunged into darkness. The household remains unperturbed though. All other appliances?whether the washing machine or the hi-fi?continue to function normally. The defective extension lead is replaced quickly and the desktop light comes on again, as though nothing had happened. A utopian prospect? Short-circuits still trigger fires in homes, cause computer crashes, and even paralyze entire municipal districts. Such disastrous consequences might soon be a thing of the past.

At Siemens Corporate Technology's Research Center in Erlangen, Dr. Dietrich Stephani demonstrates an intelligent power circuit-breaker that limits short-circuit currents like a fuse but smoothly reconnects the consumer to the distribution network after elimination of the fault, as if by magic. The secret to this is an electronic component made of silicon carbide (SiC), the same material that has been well-known as a high grade abrasive and sandpaper coating for over 100 years.
