Question

What is doping ?? Nad what is it's use ???

Answer 1

doping means adding impurity .

It is impurity added to semiconductors .

A semiconductor with impurity is called extrinsic semiconductor.

A semiconductor dopped with 3rd period rlements that is trivalrnt impurity are valled p type .

A semiconductor dopped with 5th period elements that is pentavalent impurity is called n type .

Ad in these case one electron is free that is it is not bonded to any other so it increase conductivity

Answer 2

HEY MATE HERE IS YOUR ANSWER:-

DOPING:-
Doping is the process of increasing the electrical conductivity of a pure semiconductor
by adding a suitable impurity.
