    Nice. Check out the Arrhenius plot, though...they're extrapolating from
    about a week's worth of data at 300C. Not the most persuasive data,
    even by the dubious standards of accelerated aging. They might turn out
    to be tasty to mice, for instance which of course would produce very
    large 1/f noise. ;) (This actually happened with undersea cables and
    sharks, about 20 years ago.)

    Cheers,

  2. They do the same with DVDs and claim your data will be safe for 100 years....

    Great news that it will be a while before you can blow up
    some of these, or great news that they're being developed?

    John, you brute, you're the stuff FETs--in their worst moments--dream
    of. You *are* the thing which--for them--goes bump in the night!

    My hat's off to you sir.

    Fets nshould be like wine, "We shall sell no fets before their time",
    which Nitronex sure did. GaN on silicon had/has a huge defect density.

    My engineer who was working with these things, "samples" at $125 each,
    told me he'd blown up four that morning. "Want too see?" he asked me.

    I was wondering, "What's a HEMT?" so to not appear the ignoramus I put
    it into google, and got this:
    http://en.wikipedia.org/wiki/HEMT

    It's very comprehensive, but can any of you gurun tell me if it's
    accurate? :)

    Cheers!
