I used - years ago - to work on the properties of GaAs. As far as I can recall sitting here thinking about it, GaAs might be more resistant than Si - wider band gap - but not impervious. Basically putting a huge bolt of energy into any semiconductor/semi-insulator will cause a surge of current, whose properties may or may not be ameliorated by device in which it sits; but totally resistant, no. But basically Len, if you're that close I worry about the Digilux ;-) Peter Leonard J Kapner wrote: > This is another aspect of electro-magnetic pulse (EMP) phenomenon.
