Chapter 9, Problem 9.113QP

(a)

Interpretation Introduction

Interpretation: The nitrogen doped diamonds are to be identified as examples of $\text{n}\text{or p-type}$ semiconductors. The picture of band structure that indicate the difference between pure and nitrogen doped diamond is to be drawn and the value of $E_{\text{g}}$ for nitrogen doped diamond that absorbs at $425\text{nm}$ is to be calculated.

Concept introduction: The conductivity of metalloids is enhanced by doping them with an element which has greater or lesser number of valence electrons then the metalloid element.

To determine: If the nitrogen doped diamonds are examples of $\text{n}\text{or p-type}$ semiconductors.

(b)

Interpretation Introduction

To determine: The picture of band structure that indicates the difference between pure and nitrogen doped diamond.

(c)

Interpretation Introduction

To determine: The value of $E_{\text{g}}$ for nitrogen doped diamond that absorbs at $425\text{nm}$.
