Effect of an intermediate layer with space-dependent permittivity on the ground state energy of an electron in a spherical complex nanoheterosystem

The effect of the interfaces of a multilayer spherical microcrystal on a charged particle is investigated. The case is considered where an intermediate layer with space-dependent permittivity exists near the interfaces. The dependence of the potential energy of the charged particle on distance is established by the method of the classical Green's functions. For the example of an HgS/CdS spherical structure, the energy of the ground and excited states of an electron is calculated both in the presence of an intermediate layer with space-dependent permittivity and in its absence.
