Each zone or band is readily shown to contain 2N electronic states , as may be
seen on thinking of the bands as arising from the overlap of atomic states . If each
atom has two valence electrons , there will be a total of 2N electrons , completely

The character of the electronic band scheme leading to intrinsic conductivity is
exhibited in Fig . 14 . 1 . At absolute zero we postulate a vacant conduction band ,
separated by an energy gap W , from a filled valence band . As the temperature is

If we suppose that the electrons in the conduction band behave as if they are free
, we may take the density of states in the conduction band as equal to that for free
electrons , with the energy referred to the bottom of the band . Thus , from ( 12 .
