Are others already working on bulk GaN?
You bet! And the bulk GaN research community is a tight and prestigious international club. Technologies and Devices International (TDI) is already well along in their commercialization efforts of what they call True Bulk GaN to the point where they’re already expanding their production facilities and ramping for shipments. Samples of their sliced and polished material from the boules have been out and around for almost a year now. I’ll admit I haven’t kept up with all the specifics, but I believe ATMI made excellent strides in bulk GaN sometime back, and if I remember my history correctly, researchers in Poland at Unipress have long been at it, as have the team of Les Eastman and Mike Spencer at Cornell. Then there are TDI’s peers at Kyma and Cermet who know a great deal about the subject as well and are also working diligently on growing bulk GaN. And General Electric is reported to be doing so also. Feel free to add to this knowledge base by contacting me and we’ll cover the latest
