Classify metals using energy band diagrams

1.	Classify metals using energy band diagrams
Answer» Based on the ability of various materials to CONDUCT current, the materials are classified as conductors, insulators and the semiconductors. A metal which is very good carrier of electricity is called conductor. The copper and aluminium are good examples of a conductor A very poor conductor of electricity is termed as insulator. The glass, wood, mica, diamond are the examples of an insulator. A metal having conductivity which is between conductor and an insulator is called semiconductor. The silicon and GERMANIUM are the examples of a semiconductor. This does not conduct current at LOW temperatures but as temperature increases these materials BEHAVE as good conductors..

Answer»

Based on the ability of various materials to CONDUCT current, the materials are classified as conductors,

insulators and the semiconductors.

A metal which is very good carrier of electricity is called conductor. The copper and aluminium

are good examples of a conductor

A very poor conductor of electricity is termed as insulator. The glass, wood, mica, diamond are the

examples of an insulator.

A metal having conductivity which is between conductor and an insulator is

called semiconductor. The silicon and GERMANIUM are the examples of a

semiconductor. This does not conduct current at LOW temperatures but as temperature increases

these materials BEHAVE as good conductors..
