Question

Role of doping in intrinsic semi conductor

Answer 1

Answer:

Helps in Conduction with help of impurities it conducts

Explanation:

Answer 2

Doping is the process of adding impurities to intrinsic semiconductors to alter their properties. Normally Trivalent and Pentavalent elements are used to dope Silicon and Germanium. When an intrinsic semiconductor is doped with Trivalent impurity it becomes a P-Type semiconductor.

Energy Bands in SolidsThe overlap or size of the gap between the valence and conduction bands determines the electrical conductivity of a substance. Because the band gap is so small for semiconductors, doping with small amounts of impurities can dramatically increase the conductivity of the material.
