Question

HEY MATES♥️
Why band gap decreases with increase in temperature!! ​

Answer 1

• The energy bandgap of semiconductors tends to decrease as the temperature is increased.

•This behaviour can be better

understood if one considers that

the interatomic spacing increases

when the amplitude of the atomic

vibrations increases due to the

increased thermal energy.

Answer 2

Answer:

The energy bandgap of semiconductors tends to decrease as the temperature is increased. This behaviour can be better understood if one considers that the interatomic spacing increases when the amplitude of the atomic vibrations increases due to the increased thermal energy.
