    Notes: Ensemble Monte Carlo calculations of the intersubband dynamics in binary-ternary double-heterostructure systems are presented. The presence of a ternary alloy has been explicitly incorporated to account for complexities arising from the multimode nature of phonons in real heterostructures. Electronic scattering rates are derived as a function of energy and quantum-well width for both confined and interface modes on the basis of a continuum model. Results of Monte Carlo simulations yield an intersubband time constant that is in reasonable agreement with the experimental value, but only when details of the phonon modes and their dispersion, spreading of the electronic wave functions due to poor confinement, and the phonon amplification effects are comprehensively included.
