Double quantum well structures have been used to study the compressibility of twodimensional electron gases. By using independent contacts to the two layers we are able to measure accurately the carrier density changes of the lower layer (which acts as a detector) in response to altering the top lay

Low-temperature magneto-transport and magneto-photoluminescence measurements are reported in magnetic two-dimensional electron gas samples formed by modulation doping shallow (Zn,Cd,Mn)Se single quantum wells. The small Fermi energy (βΌ1-2 meV) and large exchange-induced spin splitting (βΌ10 meV) resu
We investigated the effective magnetic field induced by spin-orbit interaction in a gated modulationdoped GaAs/AlGaAs quantum well (QW) structure. We measured the precession of the optically injected electron spins at zero magnetic field by a time-resolved Kerr rotation (TRKR) technique as a functio
A simple theory is developed for studying interactions between electrons and intense laser ΓΏelds in two-dimensional electron gases, in conjunction with recent experiments where terahertz free-electron lasers are employed as intense radiation sources in investigating optoelectronic properties of semi
