| 中文摘要 | a gaas/algaas two-dimensional electron gas (2 deg) structure with the high mobility of mu(2k) = 1.78 x 10(6) cm(2)/vs has been studied by low-temperature hall and shubnikov de hass (sdh) measurements. quantum lifetimes related to all-angle scattering events reduced from 0.64 ps to 0.52 ps after illuminating by dingle plots, and transport lifetimes related to large-angle scattering events increasing from 42.3 ps to 67.8 ps. these results show that small-angle scattering events become stronger. it is clear that small-angle scattering events can cause the variation of the widths of the quantum hall plateaus. |
