Question

can anyone describe the energy gap of semiconductors. ​

Answer 1

Answer:

Hey mate ✌️❣️

Explanation:

The lower energy level is the valence band, and thus if a gap exists between this level and the higher energy conduction band, energy must be input for electrons to become free.

Hope it helps ❣️❣️

Answer 2

Answer:

In semiconductors and insulators, electrons are confined to a number of bands of energy, and forbidden from other regions. The term "band gap" refers to the energy difference between the top of the valence band and the bottom of the conduction band. ... In contrast, a material with a large band gap is an insulator.
