Textbook Problem

The conductivity of an intrinsic semiconductor increases with increasing temperature. How can this be rationalized?

Interpretation Introduction

Interpretation:

Reason for the conductivity of an intrinsic semiconductor increases with temperature has to be explained.

Concept introduction:

A perfect semiconductor that has no impurities or lattice defects is called an intrinsic semiconductor.

Explanation

In intrinsic semiconductor, the number of electrons in the conduction band is determined by the temperature and magnitude of the band gap. Smaller the band gap, smaller the energy required to promote a certain number of electrons...
