[lotrsimp12345]

Homework Statement

What states are occupied by s-band?
What states are occupied by p-band?

Homework Equations

The Attempt at a Solution

Wouldn't s and p both be able to occupy any energy state? Since i don't know the energy level the correspond to?

so is that correct?

really confused on how to do this. Please help.

 

[lotrsimp12345]

from my reading i think their would be infinite states for both of them. Is that correct?

does this have something to do with brillouin zone and bloch states?
