We find that the energy distribution can be characterized by an effective electron temperature, T-e(&amp;gt;T-L), that agrees well with values estimated from the THz-illuminated, dc conductivity. This agreement indicates that under strong THz drive, LO phonon scattering dominates both energy and momentum relaxation; that the carrier distribution maintains a heated, thermal form; and that phonon drift effects are negligible.

We couple intense tunable far-infrared radiation from the Santa Barbara free electron laser into our sample using an edge-coupling technique and measure absorption as a function of frequency and intensity. Saturation and frequency shifts in the absorption line are clearly observed. We attribute the frequency shifts to reductions in the many-body depolarization shift. From our preliminary measurements, we estimate the intersubband relaxation time to be 600 ps to within a factor of three.&lt;/p&gt;</style></abstract><accession-num><style face="normal" font="default" size="100%">WOS:A1994NM75300061</style></accession-num><notes><style face="normal" font="default" size="100%">Sherwin, Mark S/Q-4762-2017&lt;br/&gt;Sherwin, Mark S/0000-0002-3869-1893; Markelz, Andrea/0000-0003-0443-4319&lt;br/&gt;S&lt;br/&gt;8th International Conference on Hot Carriers in Semiconductors&lt;br/&gt;Aug 16-20, 1993&lt;br/&gt;Oxford univ, oxford, england&lt;br/&gt;Sci &amp; engn res council; royal soc; brit council; oxford univ&lt;br/&gt;31</style></notes></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Allen, S.

They have the most impact on terahertz science and technology that require a tunable, high power source to explore non-linear dynamics or that sacrifice incident power to recover the linear response of systems with very small cross-section. We describe three experiments that demonstrate the utility of these lasers in experiments on the terahertz dynamics of semiconductor nanostructures: (i) terahertz dynamics of resonant tunneling diodes, (ii) saturation spectroscopy of quantum wells and (iii) photon-assisted tunneling in superlattices.&lt;/p&gt;</style></abstract><accession-num><style face="normal" font="default" size="100%">WOS:A1994NR36100065</style></accession-num><notes><style face="normal" font="default" size="100%">Sherwin, Mark S/Q-4762-2017; Guimaraes, Paulo Sergio Soares/B-6918-2012&lt;br/&gt;Sherwin, Mark S/0000-0002-3869-1893; Guimaraes, Paulo Sergio Soares/0000-0002-0113-2641; Markelz, Andrea/0000-0003-0443-4319&lt;br/&gt;1993 International Conference on Luminescence (ICL 93)&lt;br/&gt;Aug 09-13, 1993&lt;br/&gt;Univ connecticut, storrs, ct&lt;br/&gt;Univ connecticut; opt soc amer; amer phys soc; ieee, laser &amp; electro opt soc; int union pure &amp; appl phys; int sci fdn; univ connecticut res fdn&lt;br/&gt;3</style></notes></record></records></xml>
