Hello,
my question is the following:
we know from books on semiconductor physics that the energy levels of the electrons in a pure semiconductor cristal form in fact bands of energy.
I was wondering why these energy levels are in the form of bands an not simple distinct energy levels as the ones of a single atom for example.
In fact, what is the physical quantum system these energies are solution to?
Put in another way, what is the potential energy a single electron in the cristal is object to?
I have been told that Pauli exclusion principle played a certain role in the formation of the energy bands.Is this correct?
thank you
