Interactions of carriers with interface optical phonons dominate over other carrier-phonon interactions in quantum well structures for the case where well widths are less than about 30 ÅHerein, the transfer matrix technique is used to establish a formalism for determining the electrostatic potentials and dispersion relations of the interface-optical phonons for multiple-interface heterostructure systems within the framework of the the macroscopic dielectric model. This method facilitates these calculations for complex structures where the conventional method is very difficult to implement. Several specific cases are treated to illustrate the general formalism. This work was supported, in part, by ARO and ONR.
