Dynamics of a two-dimensional electron-hole system in a coupled quantum well

In this work, we have numerically integrated in space and time the effective-mass Schrodinger equation for a two-dimensional electron-hole system in a coupled quantum well system. Considering a time-dependent Hartree potential and an external electric field, we derive the nonlinear dynamical evolution of the carrier wave function. It is found that charge dynamically trapped in both wells produces a reaction field that modifies the system resonant condition. At different electron-hole sheet densities we show the possibility of multiple resonant tunneling peaks in a bilayer system. (C) 2003 American Institute of Physics.
