Time-resolved photoluminescence of two-dimensional hot carriers in GaAs-AlGaAs heterostructures

We have studied the picosecond time dependence of luminescence from a two-dimensional electron system following absorption of an ultrashort light pulse. From our measurements we determine the temporal evolution of the carrier temperature, finding that the cooling of hot carriers is suppressed by a f...
