Question

write the Extrinsic semiconductors and doping ​

Answer 1

Answer:

The conductivity of a semiconductor can be increased by doping. The process of addition of minute quantity of impurities to a semiconductor to increase its conductivity is called doping. The added impurity is called dopant.

A doped semiconductor, having higher conductivity than pure intrinsic semiconductor, is an extrinsic semiconductor.

Answer 2

Extrinsic semiconductors are semiconductors that are doped with specific impurities. ... Extrinsic semiconductors are also called impurity semiconductors or doped semiconductors. The process of adding impurities deliberately is termed as doping and the atoms that are used as an impurity are termed as dopants.
