Hot-carrier cooling in GaAs: Quantum wells versus bulk

Hot-electron cooling dynamics in photoexcited bulk and quantum-well GaAs structures were determined using time-correlated single-photon counting of photoluminescence (PL) decay. Hot-electron cooling curves were generated from analyses of the time-resolved PL spectra. The time constant characterizing the hot-electron energy-loss rate, ${\mathrm{\ensuremath{\tau}}}_{\mathrm{avg}}$, was then ...
