A theoretical investigation of electron dynamics in superlattice InGaAs/AlInAs quantum cascade lasers (QCLs) is presented, based on a Monte Carlo simulation that includes both electron–electron and electron–phonon scattering. Nonequilibrium phonons and phonon quantization effects have been explicitly considered. Calculated luminescence and gain spectra are presented. Our analysis provides a clear physical insight into the QCL operational mode. © 2002 American Institute of Physics.

    We use molecular-dynamics simulation to examine the order-disorder behavior in pure ferroelectric KNbO[sub 3] and in KNbO[sub 3]-KTaO[sub 3] ferroelectric-paraelectric solid solutions and superlattices. We find that the order-disorder behavior is remarkably robust and plays an important role in...
