OK, I've asked this before, and with a new thread on these lines, I
ask this again:

1: If a large hole current is run thru a resistor, will there be
   I^2 * R cooling instead of heating?

2: Can anyone design an amplifier that preferentially amplifies
   hole currents over normal electron currents?

3: what semiconductor materials have the highest ratio of
   hole mobility to electron mobility? (please quote actual
   test samples rather than estimates based on theory. Also,
   don't be limited to semiconductors: consider also insulators,
   resistors, dielectrics, piezo-electrics, conductors,
   magnets (metal, ceramic), magnetostrictives, etc).

NOTES:

   to summarize, this thread has so far stated that the only area
   where holes are not detectable is the vacuum. That is, hole
   particles only exist in the presence of matter.
   Previous threads have stated that holes only exist in certain
   semi-conductors. The question that naturally arises is if
   the hole currents inside a semi-conductor vanish at the point
   where the semiconductor is joined to a conductor (say, copper).
   I don't want a theoretical discussion here about whether
   holes could exist inside metal conductors, rather I ask for
   an experimental discussion on how to amplify and detect such
   currents *if* they exist.
   Also note that I have cross-posted this to sci.electronics
   since this is now becoming an electronic discussion.

Thanx,
Eric.
