Abstract
We demonstrate the application of terahertz electromagnetic transients to the study of the dynamical conductivity of a two-dimensional, high mobility electron gas in modulation-doped GaAs quantum wells. The tra nsient response of such an electron system on a picosecond time scale occurs in a regime where the implications of electron-electron interac tion effects need be considered.
