Chapter 21, Problem 21.60E

Interpretation Introduction

Interpretation:

The electron-dot type of diagram of a unit cell of $\text{GaAs}$ as well as n-type and p-type substitutions for a semiconducting material based on $\text{GaAs}$ is to be drawn. The atom which can be substituted for $\text{Ga}$ and $\text{As}$ for each type of semiconductor is to be stated.

Concept introduction:

Semiconductors are a type of conductors that have conductance in-between good conductors and insulators. There are two types of semiconductor p-type semiconductor and an n-type semiconductor. The p-type semiconductor has a hole to conduct electricity and n-type semiconductor has electrons to conduct electricity.
