Nonequilibrium quantum transport modeling in resonant tunneling photodetectors

To accurately model current-voltage characteristics in quantum-effect devices, one must abandon semiclassical single-particle approaches and turn to a more general transport theory which self-consistently accounts for the wave-like nature of electrons, particle statistics, and interaction effects. Here we present an efficient and versatile many-body nonequilibrium approach for computation of transport in device structures where quantum effects dominate. This method, based on non-equilibrium Green´s function quantum transport equations, makes it possible to consider open systems of arbitrary dimensionality having complex potentials, complex geometries, and multiple terminals
