| 中文摘要 | we obtained the high mobility of mu(2k) = 1.78 x 10(6) cm(2)/v . s in si-doped gaas/algaas two-dimensional electron gas (2deg) structures. after the sample was illuminated by a light-emitting diode in magnetic fields up to 6 t at t = 2k, we did observe the persistent photoconductivity effect and the electron density increased obviously. the electronic properties of 2deg have been studied by quantum-hall-effect and shubnikov-de haas (sdh) oscillation measurements. we found that the electron concentrations of two subbands increase simultaneity with the increasing total electron concentration, and the electron mobility also increases obviously after being illuminated. at the same time, we also found that the electronic quantum lifetime becomes shorter, and a theoretical explunation is given through the widths of integral quantum hall plateaus. |
