How may the conductivity of an intrinsic semiconductor by increased ?

1.	How may the conductivity of an intrinsic semiconductor by increased ?
Answer» Solution :The conductivity can be increased by DOPING either by ADDING electron rich impurities like that that of P, As etc. giving n -typesemicomductor or by adding electron deficit impurities like thatof B, Al etc. giving p -type semiconductor.
