Electron localization by reflection from a heterojunction

The above-barrier reflection of electrons near heterojunctions gives rise to quasilocal states with a typical lifetime of 10_ 1 '-10~9 s. An interfacial photoluminescence line due to these quasilocal states has been observed in InAs-InAsPSb heterostructures.
