Chapter 15, Problem 15E.3AE

Interpretation Introduction

Interpretation:

Arsenic-doped germanium is whether p-type or n-type semiconductor has to be identified.

Concept Introduction:

p-type semiconductor: If a group $14$ elements is doped with atoms of group $13$ elements, then an electron can be transferred from ${14}^{th}$ group element to ${13}^{th}$ group element by creating a hole in the valence band which increases the conductivity.  These types of semiconductors are called p-type semiconductors.

n-type semiconductor: If ${15}^{th}$ group elements are used as dopant for ${14}^{th}$ group elements an electron will be transferred to conduction band results in increase in conductivity.  These types of semiconductors are called n-type semiconductors.
