I still maintain that the hole doesn't "move". Holes merely appear and disappear--as electrons occupy/vacate orbitals. Movement is a "useful delusion", in the same way cinema is. The appearance of movement on the screen is a phantom created by the mind. And, in fact, the so called movement of holes isn't even seen. That's why I used the word "delusion" in association with hole movement, and illusion in terms of movie *movement. *
In fact, isn't it true that there isn't, even, a physical hole--as in some stationary pit surrounded by boundary defining electrons? I mean, in reality, it's just one less probability cloud, around the nucleus of an atom, right? So, to call that a hole, is even more delusional, right? And by delusional, I mean, a model, and not an actual thing. A useful delusion.
So, hole, is a model for a missing electron cloud -- which doesn't really resemble a hole. And, any movement of this phantom entity, is only conceptional. In an electric field, they do seem to move, but not really -- but, it's useful to think of it that way.
And, consider this: locking yourself into a way of thinking, based on an accepted model, makes it difficult to advance the field. Einstein was able to discard models and think beyond them. Because he was able to think beyond Newtonian Physics, he knocked Physics on its ear. The history of the conceptualization of the atom is another good example. If physicists had decided that the plumb pudding model was the end-all-be-all, science would not have found its way to orbitals and the to the current, very strange, model of the atom -- and it's still a model!
But, I'm not a Physicist. :P
