Abstract

We report time-resolved and continuous-wave magnetoluminescence measurements on a two-dimensional hole system in a GaAs/AlxGa1-xAs quantum well. The dominant spectral emission line in the absence of magnetic field and at high Landau-level filling factor has a short recombination lifetime, characteristic of extended hole states. Two additional lines appearing at 1/3 have long lifetimes, signaling the recombination of localized holes. The fraction of localized holes abruptly increases below =1/3.
