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".
