We present theoretical methods for the analysis of acoustic phonon modes in superlattice structures, and terahertz-frequency quantum-cascade lasers (THz QCLs). Our generalized numerical solution of the acoustic-wave equation provides good agreement w... Read More about Acoustic band engineering in terahertz quantum-cascade lasers and arbitrary superlattices.
