Question

Explain and derive conductivities of intrinsic and extrinsic semiconductors

Answer 1

HEY MATE HERE IS YOUR ANSWER...


Extrinsic Semiconductors. Intrinsic semiconductors, also called an undoped semiconductors or i-typesemiconductor, are puresemiconductor 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.


extrinsic semiconductor conductivity of intrinsic semiconductors is very less at room temperature to. increase the conductivity a small amount of external impurity is added to the puresemiconductor. such asemiconductor. ... impurities are those elements which donate excess of electrons for conduction pentavalent.
