[Amps] Electron HOLE flow

[Fuqua, Bill L]

  That is why holes can't be used to describe vacuum devices, because a hole is just that,
it is the "hole" left in an atom where there was once an electron.
 Just catching up on this thread and working my way back.

REPLY:

"Hole flow" is an illusion, much like the moving lights on a theater
marquee. If it helps to understand things fine, but holes don't move. It's
more accurate to say a hole is created in one atom and disappears in
another. For a brief time while the electron is in motion, there are
actually two holes.  Neither one "moves".
