Question

An intrinsic semiconductor, at the absolute zero temperature, behaves like which one of the following?

(a) Insulator

(b) Superconductor

(c) n-type semiconductor

(d) p-type semiconductor

This question was posed to me during an interview for a job.

Query is from Intrinsic Semiconductor in section Semiconductor Electronics : Materials, Devices and Simple Circuits of Physics – Class 12

Answer 1

The correct answer is (a) Insulator

Explanation: At the absolute zero temperature, an intrinsic semiconductor behaves like an insulator. It is an undoped semiconductor. An intrinsic semiconductor at absolute zero temperature has electrons only in the valence band.
