The electron transfer from a narrow to a wide quantum well through a thin barrier is studied in the non-resonant case by time-resolved photoluminescence. The two systems In0.53Ga0.47As/InP and GaAs/Al0.35Ga0.65As are compared. Space charge effects are investigated and discussed. Contributions of holes to the tunneling process are determined.
