Abstract
A recently proposed continuum phenomenological model for long-wavelength op tical modes in semiconductor heterostructures is employed to study mixed no npolar-polar heterosystems. Results are presented for two systems of curren t interest, namely, the wide phonon band gap Si/ZnS quantum well and narrow phonon band gap Ge/GaAs quantum well.
