intrinsic semiconductors are the pure forth group element like that Ge and Si ,
in the intrinsic there is no impurity.While on the other hand extrinsic semiconductor are impure,in it we dope some impurity like pentavelent(p) and trivelent(Al) accordingly,here we include very little amount of impurity in the intrinsic element ,so that this type we can give a overview on intrinsic ans extrinsic semiconductores.
intrinsic semiconductors are pure semiconductors.there is no impurity.and extrinsic semiconductors are conductors with impurity.when we add some impurity in semiconductors they become intrinsic semiconductors. they are of two type p type and n-type semiconductor.we use them for diode and transistor making.p type are made by doping positive ions and n type by negative ions.
Intrinsic semiconductor is a pure semiconductor which have no impurities because of which it known as Pure semiconductor.
Extrinsic semiconductor is impure semiconductor.In this semiconductor we mix one impurity atom in one billion atom of semiconductor.The process of making impurity known as doping.

1-It is pure. 1-It is impure.
2-It’s conductivity is low. 2-it,s conductivity is high.
3-we do not dope this. 3-WE dope from trivalent/ or pentavalent element.
4-it use for normal uses. 4-It use for making diode.
5-It’s resistance is high. 5-5-It’s resistance is low.
intrinsic semiconductor are the semiconductor of purest form. there is no impurity in such type of semiconductor. so there conductivity is very low as compared to extrinsic.
extrinsic semiconductor are made when impurity atom are introduced in the intrinsic type of semiconductor. if impurity is prevalent then n type and if impurity is trivalent then p type semiconductor.
An intrinsic semiconductor is chemically very pure and posseses poor conductivity. it has equal number of electrons and holes. if voltage is applied then both electron and holes contribute to current flow.
extrinsic semiconductors are good form of intrinsic semiconductors in which some impurities are added by the process known as doping, it alters the electrical property of semiconductor and make it a good conductor.doping possess two groups one negative charge(n type)and one po0sitive charge(p type)

The pure semiconductor are called intrinsic semiconductor and the impure semiconductor are called extrinsic semiconductor. Various impurities are added to pure semiconductor to make it extrinsic. Trivalent or pentavalent impurities are prefferd. By adding impurities we can increase the conductivity of the semiconductor. P(due to trivalent) and n(due to pentavalent) type semiconductor are the examples of extrinsic semiconductor.
An intrinsic semiconductor, also called an undoped semiconductor or i-type semiconductor, is a pure semiconductor without any significant dopant species present. The number of charge carriers is therefore determined by the properties of the material itself instead of the amount of impurities.
and the Extrinsic Semiconductor is nothing but An extrinsic semiconductor is a semiconductor that has been doped, that is, into which a doping agent has been introduced, giving it different electrical properties than the intrinsic (pure) semiconductor.
