Synthetic Industrial Diamonds

[AstroEngineer]

Has anyone used Centaurus or E6 diamonds or related materials in semi conductor applications?. Centaurus uses MagFlux and E6 uses CVD processes respectively.

It's my understanding that these diamonds and/or related materials are great for semi-conductors.

Any help is appreciated in regards to applications. I see CERN is using E6 products currently.

I'm doing research for a future project and focusing on viable materials.

Any comments on the process, consistency, applications, and known issues (Pros/Cons) are welcome. Thanks.

"semi conductor applications?"

Huh?

Yes. As in...

Synthetic diamond has potential uses as a semiconductor,[75] because it can be doped with impurities like boron and phosphorus. Since these elements contain one more or one less valence electron than carbon, they turn synthetic diamond into p-type or n-type semiconductor. Making a p–n junction by sequential doping of synthetic diamond with boron and phosphorus produces light-emitting diodes (LEDs) producing UV light of 235 nm.[76] Another useful property of synthetic diamond for electronics is high carrier mobility, which reaches 4500 cm2/(V·s) for electrons in single-crystal CVD diamond.[77] High mobility is favorable for high-frequency field-effect transistors. The wide band gap of diamond (5.5 eV) gives it excellent dielectric properties. Combined with the high mechanical stability of diamond, those properties are being used in prototype high-power switches for power stations.[78]
Synthetic diamond transistors have been produced in the laboratory. They are functional at much higher temperatures than silicon devices, and are resistant to chemical and radiation damage. While no diamond transistors have yet been successfully integrated into commercial electronics, they are promising for use in exceptionally high power situations and hostile non-oxidizing environments.[79][80]

Any experience? Where does this field stand now commercially? Products available now and if so Pros/Cons. TIA.

The answer is neither. One is primarily making synthetic jewelry diamonds, while the other is making rather tiny substrates; their single-crystal substrates are barely 1/5" in size:

Unfortunate, Thanks.
