| Abstract | From a general viewpoint, the binding energy of the excitons in type-II hetero-quantum-wells with the presence of a dielectric mismatch is discussed by making use of image potentials, variational method and infinite-potential-barrier model. The calculation is performed for various parameters including the electron-hole mass ratio sigma, dielectric constant ratio delta and well width d. A static Gabovish-type potential is engaged to describe the image potential inside the well. It is found that the image potential may play an important role in the formation of the excitons. The contribution of image potentials to the binding energy is compared with binding energy for two kinds of type-II hetero-QWs, GaSb-InAs-GaSb and AlAs-GaAs-AlAs. In these two cases, the image potentials are above 10% of the corresponding binding energies. |
