Chapter 21, Problem 21.21QP

Interpretation Introduction

Interpretation:

The general characteristic of n-type semiconductors and p-type semiconductors has to be described.

Concept introduction:

n-type semiconductors: Solid semiconducting material having donor impurities are said to be n-type semiconductors, where “n” indicates negative which means the charge of the extra electron.

p-type semiconductors: Semiconducting material having acceptor impurities are said to be p-type semiconductors, where p indicates positive.

Donor impurities: Conduction elements producing impurities are said to be donor impurities.

Acceptor impurities: Impurities which are electron deficient are said to be acceptor impurities.
