Question

What are energy bands? Write any two distinguish features between conductors , semiconductor and insulators on the basis of energy band diagrams. How does the change in temperature affect the behavior of these materials? explain briefly

Answer 1

Answers are given below.

Explanation:

What are energy bands?

A set closely spaced energy levels in a large number in crystalline material are known as energy levels. The energy levels that exist as individual levels of energy surrounded by electrons are known as energy bands.

Distinguish features between conductors, semiconductor and insulator?

• The main difference between conductors and insulators is the conduction of electric current.
• The conductors conduct electricity while insulators don not.
• Whereas semiconductors sometimes conduct and sometimes do not.
