Chapter 8, Problem 8.29PAE

Interpretation Introduction

Interpretation: doping affects the electronic properties of a semiconductor has to be determined.

Concept introduction:

• Semi-conductors can be intrinsic (pure) or extrinsic (doped).
• Extrinsic semi-conductors are of two types: n-type and p-type
• N-type semi-conductors are produced when an intrinsic semi-conductor is doped with donor atoms. P-type semi-conductors are produced when an intrinsic semi-conductor is doped with acceptor atoms.
• The impurity atoms acting as dopants, change the electron-hole concentration in the semi-conductors, thus affecting the electronic properties.
