The bandgap of a material is the energy difference between electrons residing in the two most important states of a material-valence band states and conduction band states.
The number of electrons in the bound and conduction band has been calculated using inhomogeneity model.
[FIGURE 4 OMITTED] In the amorphous semiconductor materials, the optical transition is from the valence-band tail states to the conduction band and from the extended states in the valence band to the conduction-band tail states (14).
