Question
Chapter 21, Problem 21.62E
Interpretation Introduction
Interpretation:
The explanation for electricity conductance by the hole is to be stated.
Concept introduction:
Semiconductors are a type of conductors that have conductance in-between good conductors and insulators. There are two types of semiconductor p-type semiconductor and an n-type semiconductor. The p-type semiconductor has a hole to conduct electricity and n-type semiconductor has electrons to conduct electricity.
