| 英文摘要 | By using time-resolved photoluminescence and time-resolved kerr rotation, we have studied the unique electron spin dynamics in inas monolayer (ml) and submonolayer (sml), which were sandwiched in gaas matrix. under non-resonant excitation, the spin relaxation lifetimes of 3.4 ns and 0.48 ns were observed for 1/3 ml and i ml inas samples, respectively. more interestingly, the spin lifetime of the 1/3 ml inas decreased dramatically under resonant excitation, down to 70 ps, while the spin lifetime of the 1 ml sample did not vary much, changing only from 400 to 340 ps. these interesting results come from the different electron-hole interactions caused by different spatial electron-hole correlation, and they provide a direct evidence of the dominant spin relaxation process, i.e. the bap mechanism. furthermore, these new results may provide a valuable enlightenment in controlling the spin relaxation and in seeking new material systems for spintronics application. |
