Textbook Problem

A 0.132-mole sample of an unknown semiconducting material with the formula XY has a mass of 19.0 g. The element X has an electron configuration of [Kr]5s24d10. What is this semiconducting material? A small amount of the Y atoms in the semiconductor is replaced with an equivalent amount of atoms with an electron configuration of [Ar]4s23d104p5. Does this correspond to n-type or p-type doping?

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.

Molarmass=Massgmole......(1)

Explanation

Explanation

Record the given data:

Electron configuration ofelement X = [Kr]5s24d10 .

Mass of semiconductor = 19.0 g .

Mole of semiconductor = 0.132 mole .

Electron configuration of dopant = [Ar]4s23d104p5 .

The electron configuration of element X, mass and mole of semiconductor are record as to shown above.

To determine the given semiconductor substance

The electron configuration Cadmium = [Kr]5s24d10

X = Cadmium
