| Abstract: | Time-integrated and time-resolved photoluminescence studies of GaAs-AlAs single quantum wells under hydrostatic pressure were performed at 77 K. The Γ-point exciton luminescence quenches when the luminescence peak energy approaches 1.83 eV under hydrostatic pressure. The quenching is ascribed to the interlayer Γ-X crossing. Photoluminescence shows anomalously slow decay ranging from several nanoseconds to a few tens of nanoseconds under low hydrostatic pressure. With the further increase of hydrostatic pressure, the luminescence rise decreases drastically and is less than a few tens of picoseconds around the interlayer Γ-X crossover. The appearance of the slow decay component and the sudden decrease in the rise time are explained by the interlayer Γ-X transfer of electrons. |
