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

Options

A. Intrinsic
B. Extrinsic
C. Donor
D. acceptor

Answer

A

Explanation

In intrinsic semiconductor, conductivity increases with rise of temperature due to rupture of covalent bonds and thus charge carriers become available.
In extrinsic semiconductor, conductivity increases due to doping and also due to rupture of covalent bonds with rise of temperature.
