Abstract

An investigation of the hot carrier relaxation in GaAs/(AlGa)As quantum wells and bulk GaAs in the high carrier density limit is presented. Using a time-resolved luminescence up-conversion technique with <or=80 fs temporal resolution, carrier temperatures are measured in the 100 fs to 2 ns range. The results show that hot carrier cooling in quantum wells becomes significantly slower than in the bulk for carrier densities greater than 2*10 ¹⁸ cm^-3.
