Energy Band#!#Semiconductor

The forbidden energy band gap in conductors, semiconductors and insulators are EG_(1), EG_(2) and EG_(3) respectively. How are they related?

The energy band gap (difference between conductor band and valance band) in semiconductors is

The forbidden energy band gap in conductors, semiconductors and insulators are EG_(1), EG_(2) and EG_(3) respectively. The relation among them is

Assertion : The electrons in the conduction band have higher energy than those in the valence band of a semiconductor Reason : The conduction band lies above the energy gap and valence band lies below the energy gap.

Explain the formation of energy band diagram in case of conductor and semiconductor.

Statement-1 : When the temperature of a semiconductor is increased, then its resistance decreases. Statement-2 : The energy gap between conduction band and valence band is very small for semiconductor.
