Abstract:
The authors discusss exciton energies in a thin film with d thickness and influence of the edge polarization upon the excitons.The polarization is described as interaction between electron(hole) and its image charge.It is found that the interaction decreases the exciton energies to some extent and the influence of the interaction upon the films possessing different dielectric constants and with different thickness are different.
