Conduction band: Its a band representing the total number
of electrons(of all atoms of a semiconductor material)
available for conduction.
For an n-type semiconductor,conduction band contains large
number of electrons & for p-type semiconductor, CB contains
few number of electrons.
Valence Band: Its a band representing the total number of
holes of all atoms of a semiconductor material.
For an n-type semiconductor,valence band contains few
number of holes & for p-type semiconductor, VB contains
large number of holes.
Conduction band is at a higher energy level than valence
band
