But we went with AlN, which is almost as good thermally. What - you aren't using slabs of vapour-deposited diamond! No wonder the venture capitalists have stopped dropping in. Not only does it have very high thermal conductivity, but it is also environmentally sound - fixing carbon that would otherwise contribute to global warming. -- Bill Sloman, Nijmegen

We work with one group that's doing B-52 radar upgrades; they were Sanders Associates before being acquired by BAE. They tell me that, because of security rules, they can tell me stuff they aren't allowed to communicate to the home office in Europe. The B-52's are scheduled to be retired in 2040, at which time they'll be 80 years old. John

I wish I could machine all my heatsinks out of isotopically pure diamond, which is something like 10x a better heat conductor than the junky stuff. The cool new semiconductor is GaN on diamond. The ultimate would be an AlN fet on isotopically pure diamond, but I hear there are materials problems to be resolved. GaN on silicon ain't bad, though. We've been blowing up\\\\\\\\ evaluating some impressive parts lately. > >No wonder the venture capitalists have stopped dropping in. > The last time I dealt with VCs, it was in a conference room in Palo Alto with 6 lawers present, running roughly $2k per hour for my side alone. They are, in general, loathsome creeps. We won. VC's don't invest in companies, they circle them in the desert, wait until they weaken, and fly down to pick their still-living flesh. They encourage owners to keep spending, string out negotiations until they are desperate, then immediately re-incorporate in Delaware with terms and conditions that would make Al Capone blush. Titles then change from things like "President/Founder" to "Chief Scientist/Slave." >Not only does it have very high thermal conductivity, but it is also >environmentally sound - fixing carbon that would otherwise contribute >to global warming. It would make great auto windshields. And you could build all-transparent buildings. John |
