Thank you
I realize that electrons are usually considered indistinguishable - your answer is a bit helpful -you seem to have said that an electron raised from a localized state (in the forbidden band) to the CB can be said to occupy a certain "fuzzy volume" for a certain amount of equally...
Recently there was a discussion concerning whether an electron in the conduction band was localized or delocalized. The back and forth arguments seemed inconclusive, difficult to follow (too brief too couched in jargon/unrealistic models) and ended in something close to insults back and forth...
