Question

In the case of semiconductors, the valence and conduction bands ______.

विकल्प

• do not overlap, energy gap is large

• overlap, energy gap = 0

• do not overlap, energy gap = 0

• do not overlap, energy gap is small

Answer 1

In the case of semiconductors, the valence and conduction bands do not overlap, energy gap is small.

Explanation:

Semiconductors have an energy gap that falls in between conductors and insulators. 

This difference is usually around 1 eV.
