(E(omega)), of a quasi 2D electron gas on the amplitude E(omega) and frequency of intense, far-infrared fields (omega/2pi = 0.24-3.5 THz). We measure sigma(d.c.) (E(omega) parallel-to E(d.c.)), where E(d.c.) is a small sensing field, and observe a monotonic decrease in sigma(d.c.) with increasing E(omega). Although a simple scaling ansatz collapses the measured sigma(d.c.) (E(omega)) data onto a single curve for frequencies from 0.25-3.45 THz (at low to moderate scaled fields), the decrease in conductivity is substantially more rapid than expected from comparison to similar data taken by Masselink et al. [Solid-St. Electron. 31, 337 (1988)] at 35 GHz. We tentatively attribute this difference to effects of a high-frequency modulation in the electron temperature.&lt;/p&gt;</style></abstract><accession-num><style face="normal" font="default" size="100%">WOS:A1994NE79600042</style></accession-num><notes><style face="normal" font="default" size="100%">Markelz, Andrea/0000-0003-0443-4319&lt;br/&gt;6th International Conference on Modulated Semiconductor Structures&lt;br/&gt;Aug 23-27, 1993&lt;br/&gt;Garmisch partenkir, germany&lt;br/&gt;Tech univ munchen, walter schottky inst&lt;br/&gt;1</style></notes></record></records></xml>
