| Abstract: | Basing on the Hamiltonian of surface polaron proposed by Sak, J., we constructed the Hamiltonian of surface exciton, considering the influence of the dispersion of acoustic phonon upon the surface excitons we calculated the energy of surface exciton with the method adopted by Haga and discussed the relations between the polarons and the excitons. |
