✦ Synopsis

The collective oscillations of a 2D quantum well electron plasma embedded in a semiinfinite host plasma medium (at a distance z 0 from the surface) are analyzed here, based on an explicit inversion of the joint dielectric function of the combined system in position representation in closed form. The coupling of surface and bulk plasmons of the host medium with intersubband and intrasubband plasmons of the quantum well, and the dependence of the coupled modes on z 0 are discussed.
