Abstract
AbstractThe flux averaging method for time‐dependent calculations of resonant tunneling probabilities is generalized for the case of multichannel scattering by analyzing a generic model for resonant tunneling in a molecular junction with N terminals (N open scattering channels). The transmission probability between any two channels is expressed as a weighted average of time integrals over probability fluxes through different spatial contours. In the case of resonance scattering the transmission probability is shown to converge within a (short) direct‐scattering timescale, circumventing the problem of slow convergence of each one of the time integrals due to population of a long‐lived resonance state. © 2004 Wiley Periodicals, Inc.
