"Cree" is a small company that makes chips out of silicon carbide.
In addition to being one of the hardest materials known to man, this
stuff can withstand much higher temperatures and power levels than
silicon. Also, when made into diodes, it gives off blue light, a
rarity. The problem with this compound is imperfections in the crystals
and difficulty in working with it.
Does anyone out there know whether this technology has a profit-
generating potential in the near future?
