Intrinsic

Vedclass · Answer

(C) An intrinsic semiconductor is a pure semiconductor material in which the electrical conductivity is solely due to the thermal excitation of electrons from the valence band to the conduction band,which involves the breaking of covalent bonds.In contrast,an extrinsic semiconductor is a semiconductor that has been doped with impurities to increase its conductivity,meaning its conductivity is due to both the breaking of covalent bonds and the presence of excess charge carriers introduced by the impurity atoms.Therefore,when conductivity is due to the breaking of covalent bonds in a pure material,it is classified as an intrinsic semiconductor.

When the electrical conductivity of a semiconductor is due to the breaking of its covalent bonds,then the semiconductor is said to be
