Abstract:
We obtain the work classically necessary to generate an ensemble of two charges, one placed in the core and the other in the shell, for a core-shell spherical system (CSSS). The CSSS has different dielectric function of the core and shell and is embedded in environment characterized by another (a third one) dielectric constant. The charge polarization is also obtained. The expressions are verified by comparison with the expressions obtained for the simpler problem of Brus [1].
