Chapter 21, Problem 21.19QP

Interpretation Introduction

Interpretation:

The terms conductor, insulator, semiconducting elements, donor impurities, acceptor impurities, n-type semiconductors, and p-type semiconductors has to be defined.

Concept introduction:

Conductor: A conductor is a material which allows the flow of an electrical current.

Insulator: An insulator is a material which does not allows the flow of an electrical current.

Semiconducting elements: Semiconducting elements are partially allows flow of an electrical current.

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.

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.
