What is the need for doping an intrinsic semiconductor?

1.	What is the need for doping an intrinsic semiconductor?
Answer» The electric conductivity of an intrinsic semiconductor is very low at room temperature; hence no electronic devices can be fabricated using them. Addition of a small amount of a suitable impurity to an intrinsic semiconductor increases its conductivity appreciably. Hence, intrinsic semiconductors are doped with impurities.
