If not: then how do the holes in a semiconductor manage to conduct electricity (if they can't travel through the solid)?
If there are:
1) then what is the difference between the valence and the conduction band?
2) then why do the electrons in a semiconductor need to reach the conduction band to conduct? (cause they should also be able to conduct the current through the valence band)
I thank you very much!
EDIT: for the purists, of course I don't mean an actual free electron, just one that can travel through the solid
