Abstract:
We report a set of transient photoluminescence TPL measurements of GaAs and AlGaAs double heterostructure DH materials as a function of temperature from 10K to 300K. We also report measurements of the time-integrated photoluminescence spectra of these samples. We observe, in both the spectra and the TPL measurements, evidence that the low-temperature photoluminescence kinetics are affected by additional paths for radiative decay that are not evident at room temperature, but have implications for material qualities measured at room temperature.
