I am also looking for a good explanations for bloch functions and beriluen zone..why we have it and what is the meaning... And the last issue I am interested in what are the determination rules in quantum dots ( I mean spectroscopic rules)?

There isn't a real explanation there for the phenomenon as I have asked. i didn't ask what is it.

Can anybody explain my what is the origin of this forbidden gap? I mean how it was created and what is the physics behind this issue?
