bandoffset
Band offset, also referred to as bandoffset, is the difference in energy between the band edges of two materials at a semiconductor heterojunction. When two semiconductors are brought into contact, their conduction-band minima and valence-band maxima realign to form a potential step, creating a conduction-band offset and a valence-band offset.
These offsets determine the type of band alignment: type I, type II, or type III, which in
Practically, ΔEc and ΔEv are related by ΔEc + ΔEv ≈ Eg1 − Eg2, where Eg1 and Eg2 are
Band offsets are central to the design of optoelectronic devices, including quantum-well LEDs and lasers, high-electron-mobility
