Semiconductors thus have a very small band gap,
meaning that their conductivity is in between that
of an insulator and conductor. P- type conductors
create an abundance of holes while n-types create
an abundance of negatively charged carriers
(conduction electrons) for the host material. The impurity added in p- type semiconductor
provides extra electrons known as Donor atom,
whereas in n- type semiconductor impurity added
creates a vacancy of electrons called holes and
termed as Acceptor atom. In a p- type
semiconductor , the majority carriers are holes, and
minority carriers are electrons.
