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.

Blurred answer
Students have asked these similar questions
a) Explain the band structure of an electrical conductor (metal), a semiconductor, and an insulator at 0 K by showing the valence and conduction bands and fermi energy levels. Explain how the electrical conduction takes place in these three types of materials. Give an example for each type of material. b)Explain what n and p-type semiconductors are using their band structures. Why?
Choose the options that would form a p-type semiconductor.  Choose all that would make a p-type semiconductor, there may be more than one. Antimony doped with Germanium   Germanium doped with Phosphorus    Tin doped with Arsenic   Silicon doped with Aluminum   Arsenic doped with Tellurium
What do Doped semiconductors contain?
