Interpretation Introduction

(a)

Interpretation:

The dopants required to make GaAs a p-type semiconductor is to be stated.

Concept introduction:

A semiconductor is type of conductor that has conductance in-between good conductors and insulators. There are two types of semiconductors, that is, p-type semiconductor and an n-type semiconductor. The p-type semiconductor has holes to conduct electricity and n-type semiconductor has electrons to conduct electricity.
