The band gap is typically in the range of 1-4 eV.
Around the band gap, the Faraday effect shows resonance behavior.
The materials in these are semiconductors with narrow band gaps.
It can be shown that the energies of these states all lie within the band gap.
Both phases have a band gap of about 3 eV.
There are no available states in the band gap.
Thus we observe an increase in the apparent band gap.
In general, the greater the wurtzite component, the larger the band gap.
In contrast, a material with a large band gap is an insulator.
For this to occur, energy is required, as in the semiconductor the next higher states lie above the band gap.
A semiconductor has an energy gap within which no electron can move or exist with that energy.
The range of the energy gap is from 0.5 to 0.6 eV.
It displays an inverted band structure, and the optical energy gap, e, is less than 0.
This two-way interaction arises because the energy gap in either direction is similar.
Energy levels from quantum states in two different shells will be separated by a relatively large energy gap.
It is a semiconductor with a large energy gap of around 3 eV.
Metals are special, because they have no energy gap at all.
For silver, the energy gap widens and it becomes silvery.
This has nothing to do with energy efficiency or plugging the energy gap.
Fears of a future energy gap could, of course, turn out to be unfounded.
