Question

Explain classification of materials based on band theory of solids

Answer 1

Answer:

on the basis of energy band materials are classified as insulators conductors and semiconductors as insulator substance like wood class means which do not follow the passage of current through them are known insulators and also the valence band of the substances is full per as he conduction band is completely empty..

hope this helps you..

Answer 2

On the basis of classification of materials based on theory of solids metals are categorized into 3 parts -

1. Conductors - An electrical conductor is a substance in which electrical charge carriers, usually electrons, move easily from atom to atom with the application of voltage.

2. Insulators - An electrical insulator is a material whose internal electric charges do not flow freely; very little electric current will flow through it under the influence of an electric field

3. Semi- Conductors - A semi - conductor material has an electrical conductivity value falling between that of a conductor, such as metallic copper, and an insulator, such as glass. ...
