Abstract

The energy spectra of all types of free vibrations existing in combined nanoheterosystem consisting of cylindrical semiconductor quantum dot, semiconductor quantum ring embedded into the quantum well placed in water are studied in the framework of dielectric continuum model. It is shown that depending on the boundary conditions for the potentials of polarization fields there are two types of interface phonon modes: top (bottom) surface optical (TSO) modes and side surface optical (SSO) modes..
