摘要
For a double layer 2D hole system, a maximum in velocity shift at upsilon = 1 was only observed at frequencies above 560 MHz. The background velocity shift in the region where the Fermi level lies in the extended states region was observed to increase with increasing frequency. Anomalous bipolar peaks centred at 1, 2 and 4 have been observed for high temperatures and powers in the longitudinal acoustoelectric effect at 0.8 GHz. (C) 2002 Elsevier Science B.V.
