Hey!!
Heterojunction Band Alignment
The central feature of a heterojunction is that the bandgaps of the participating semiconductors are usually different. Thus, the energy of the carriers at at least one of the band edges must change as those carriers pass through the heterojunction. Most often, there will be discontinuities in both the conduction and valence band. These discontinuities are the origin of most of the useful properties of heterojunctions.
As with all semiconductor devices, the key to understanding the behavior of heterojunctions is the energy-band profile which graphs the energy of the conduction and valence band edges versus position. The position-dependent band-edge energies are just the total potential appearing in (3), and we will use the symbols and to denote these quantities for the conduction and valence bands, respectively.
Hope it's help you..!!!
