According to the band theory, how does a crystalline material that has one electron per unit cell behave?

Expert Solution

Now in this case of one electron per unit cell the, because of the spin we get,

which gives us the first brillouinn zone at Pi/2a and is

Now with the crystal potential the energy inside the First Brillouin Zone is lower close to the zone boundary and hence the Fermi surface is extended towards the zone boundary as it get's closer.
