Nanodiamond

Could I resist reading a story with that title? No.
Researchers at Vanderbilt University are making electronics out of diamonds rather than silicon. The "nano" part is due to the very thin layer that is used; the process is inexpensive because of this, and also due to the use of industrial diamonds (or what should be called "reasonably-priced" diamond). Why do this when silicon seems to be adequate? Well, silicon has problems with high-energy particle interference, e.g when in space or in a nuclear reactor. These new-style transistors get around that by using an old-style concept: vacuum tubes. Yes, if they can cheaply pack these in a vacuum, we will have Super-efficient Nanodiamond Space Transistors. And who doesn't want one of those?
