Abstract

Continuous-wave and time-resolved photoluminescence at low temperatures is investigated in near-surface quantum wells, where carrier tunneling to surface states reduces the el-hhl excitonic emission efficiency. Analysis of the time-resolved spectra points to a behavior for strained InGaAs/GaAs structures different from AlGaAs/GaAs interfaces, in that tunneling occurs not only from the free-carrier continuum, but also from the exciton ground state.
