Question

How does the conductivity of an intrinsic semiconductor compare with that of an extrinsic semiconductor?

Options

• Intrinsic conductivity is relatively low; extrinsic conductivity is higher.

• Intrinsic conductivity is higher; extrinsic conductivity is relatively low.

• Both always have the same conductivity.

• Neither can conduct at any temperature.

Answer 1

An intrinsic semiconductor has relatively low conductivity. An extrinsic semiconductor has higher conductivity than an intrinsic semiconductor.
