ELECTRIC-FIELD TRANSPORT IN A 2-DIMENSIONAL ALGAAS GAAS HETEROSTRUCTURE/

A quantum non-linear theory for transport that includes many body effe cts is applied to a two-dimensional electron gas in an AlGaAs/GaAs het erostructure. Two formulations that result from the theory are employe d in investigations of the transient and steady state behavior of the electronic velocity and the hot electron temperature. Calculations usi ng both approaches in the transient state are compared with available Monte Carlo results. Calculations for the steady state are compared wi th experimental data.
