Chapter 12, Problem 23PS

Interpretation Introduction

Interpretation:

The intrinsic semiconductor and extrinsic semiconductors has to be defined with examples.

Concept introduction:

Semiconductor:

Semiconductors will conduct the electric current more easily.

Intrinsic semiconductor:

Naturally occurring property of pure material, the number of electrons in the conduction band is determined by the temperature and magnitude of the band gap.

If the gap is small and very small energy is required to promote the electrons.

Extrinsic semiconductors:

The conductivity of these materials is controlled by adding different atoms called dopants.
