Yousef & Maxwell,

Excuse my butting in, but an electron can move relatively freely under a potential in the conduction band proliferated with empty states, while a hole must be nudged along by electrons "backfilling" in the empty state that the hole represents in the valence band. One might make an analogy with a drop of water falling and a bubble rising (I can't think of a better one right now). As for an electron being a "real physical entity," there is no such thing as "real".

Pravin.
