Chapter 9, Problem 147IP

Interpretation Introduction

Interpretation:

The given semiconductor should be identified and after doping the produced semiconductor type should be determined.

Concept Introduction:

Semiconductor:

The electrical conductivity of the substance increases when the temperature increases.

In normal temperature conductivity of the substance is equal to insulator.

N-type semiconductor:

The host substance is doped by more valence electrons containing substance give n-type semiconductor.

The conductivity of the host substance is increases when the valence electrons containing substance are doped.

P-type semiconductor:

The host substance is doped by less valence electrons containing substance give p-type semiconductor.

Molar mass:

The mole present in the gram of substance is called molar mass.

$\text{Molar}\text{mass}\text{=}\frac{\text{Mass}\text{g}}{\text{mole}}\mathrm{......}(1)$
