Chapter 6, Problem 23Q
Interpretation Introduction

Interpretation:

Whether the given diagram represents p-type silicon semiconductor or n-type silicon semiconductor has to be explained.

Concept Introduction:

n-type semiconductor:

  In this type of semiconductors, conductivity is increased by doping an element with 5 valence electrons (i.e. doped atom acts as a donor impurity).

p-type semiconductor:

  In this type of semiconductors, conductivity is increased by doping an element with 3 valence electrons (i.e. doped atom acts as an acceptor impurity).
