| 英文摘要 | Using time-resolved photoluminescence and time-resolved kerr rotation spectroscopy, we explore the unique electron spin behavior in an inas submonolayer sandwiched in a gaas matrix, which shows very different spin characteristics under resonant and non-resonant excitations. while a very long spin relaxation lifetime of a few nanoseconds at low temperature is observed under non-resonant excitation, it decreases dramatically under resonant excitation. these interesting results are attributed to the difference in electron-hole interactions caused by non-geminate or geminate capture of photo-generated electron-hole pairs in the two excitation cases, and provide a direct verification of the electron-hole spatial correlation effect on electron spin relaxation.
