Paper Abstract

A series of GaAs/AlGaAs multiple quantum well (MQW) structures, modulation or antimodulation doped, has been grown by molecular beam epitaxy. The samples were identical apart from the doping, the level of which was varied between 1.5 x 1012 cm-2 and 9 x 1012 am-2; in each case the doping was carried out in such a way as to retain approximately square potentials in the wells. Far infrared measurements on the plasma response were made using dispersive Fourier transform spectroscopy (DFTS), oblique incidence reflectivity, and attenuated total reflection (ATR) spectroscopy.
