What's Your Question?
Answer
It is the gap between conduction band and valance band.It is more for insulator and no for conductors. 0.3 to 0.7 eV for semiconductors
Answer
The gap between the conduction band and valence band is called energy band gap.
Answer

Energy gap:

In solid-state physics, an energy gap is an energy range in a solid where no electron states exist, i.e. an energy range where the density of states vanishes. Especially in condensed-matter physics, an energy gap is often known More abstractly as a spectral gap, a term which need not be specific to electrons or solids.

Answer

 

Band gap

A band gap is the distance between the valence band of electrons and the conduction band. Essentially, the band gap represents the minimum energy that is required to excite an electron up to a state in the conduction band where it can participate in conduction.[1] 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. The size and existence of this band gap allows one to visualize the difference between conductors, semiconductors, and insulators

Answer
The energy required to move the electrons fromm the conduction band to the valence band is called energy gap of the semiconductor. This can also be called as band gap.
