GaNの話

Gallium nitride (GaN) is a better semiconductor than silicon. There are many crystals that are better than silicon, but the problem has always been that they are far too expensive to be used in every application where silicon is used. But, GaN can be grown as an inexpensive thin layer on top of a standard silicon wafer enabling devices that are faster, smaller, more efficient, and less costly than their aging silicon counterparts.

2016年1月、私は、そのとき、来る年のいくつかの予測をしました。無線充電、拡張現実、自動運転車、医療診断やインターネット・アクセスの進歩など、新しい市場に対する予測をしました。これらの市場における進歩は、すべての面で、予想よりも、時にはより速く、時にはより遅くなりました。そして、ここで、私たちは、まさに新しい年を迎えようとしており、おそらく、愚かなことに、私は、再び未来を予測しようと思います。

In past postings , we looked at the applications that have emerged because of new capabilities available with #GaN technology. We also discussed the transformational nature of some of these applications in areas like medicine, telecommunications,human-machine interfaces, and the delivery of electrical power itself (wireless power transfer). GaN technology is entering an era similar to the 80’s and 90’s when the utility of technological improvement was apparent across broad commercial markets. Consequentially, consumers will be willing to pay a premium for the life-style improvements enabled by these improvements thereby accelerating growth of GaN applications for the foreseeable future.

The demand by our society for information is growing at an unprecedented rate. With emerging technologies, such as cloud computing and the internet of things (IoT), this trend for more and faster access to information is showing no signs of slowing. What makes the transfer of information at high rates of speed possible are racks and racks of servers, mostly located in centralized data centers.
