RE unclewest: "the advantage cree has is SiC is considerably less expensive than sapphire and is technically superior. "

One of the articles I read this week stated that SiC is "two orders of magnitude more expensive than sapphire". They were speaking of the price of wafers. I will try to go back and find which article this was, and make sure it is not woefully out of date.

I agree with you about SiC being technically superior to sapphire as a base for growing blue LED's. It has a better latice match to GaN, conducts heat far better, and can be made electrically conductive allowing one of the two contacts to be put on the bottom. But are you sure it's less expensive?
