Chapter 12, Problem 69E

Interpretation Introduction

Interpretation:

The element that replaces gallium in $\text{GaAs}$ to produce $\text{n}-\text{type}$ semiconductor is to be determined.

Concept Introduction: The element used to replace an element of the semiconductor in the doping process to create an $\text{n}-\text{type}$ semiconductor should be of the similar size and should have one more valence electron than that of the element of the semiconductor.

To determine: The element that replaces gallium in $\text{GaAs}$ to produce $\text{n}-\text{type}$ semiconductor.
