Chapter 12, Problem 6E

Interpretation Introduction

Interpretation:

The valence and conduction band of the given semiconductor is to be stated. The band which consists bonding molecular orbitals is to be stated. Whether it is n-type or p-type semiconductor is to be explained and the correct dopant for germanium is to be identified.

Concept introduction: Semiconductor is defined as a substance whose electrical conductivity lies between the metal and the insulator. The semiconductor consists of two bands, a band that contains electrons is the valence band and the empty band is known as conduction band.

(a)

To determine:

The valance band.

(b)

Interpretation Introduction

To determine:

The conduction band.

(c)

Interpretation Introduction

To determine:

The band that consists of bonding molecular orbital.

(d)

Interpretation Introduction

To determine:

The given semiconductor is n-type or p-type.

(e)

Interpretation Introduction

To determine:

The dopant for germanium semiconductor.
