Investigation of inter-valley scattering and hot phonon dynamics in GaAs quantum wells using femtosecond luminescence intensity correlation
Superlattices and Microstructures 6:2 (1989) 199-202
Abstract:
Photoluminescence intensity correlation measurements of GaAs quantum wells using 120 fs laser pulses show relatively slow relaxation times ≤ 10 ps at high energy close to the L valley conduction band minimum. This value is consistent with recent measurements of the L → Γ scattering time. However, theoretical estimates show that nonequilibrium phonon effects can also give rise to slow relaxation on this timescale.INVESTIGATION OF INTER-VALLEY SCATTERING AND HOT PHONON DYNAMICS IN GAAS QUANTUM WELLS USING FEMTOSECOND LUMINESCENCE INTENSITY CORRELATION
