Abstract:
We study numerically the time development of the phonon packets propagating through the single- and double-superlattice systems. In a single superlattice system, we find the time advance and delay for the transmitted and reflected phonon packets, respectively. In a double superlattice system in which the resonant transmission occurs, we find large time delays for both the transmitted and reflected packets when the spectrum of the incident packet has a large component at the resonance frequency. These results are well understood in terms of the phase time defined by the stationary phase analysis.
