Question

Distinguish between 'intrinsic' and 'extrinsic' semiconductors.

Answer 1

1.the electrical conductivity of intrinsic semiconductor is low while in extrinsic semiconducor is high

2.the no. of density of electron is equal to the no. of density of holes i.e ne=nh while in extrinsic ne is not equal to nh
