Spectral diffusion for type-II excitons are different from type-I excitons, in the point that electrons and holes are localized in different layers. The deformation potentials of the valence (conduction) band of both the InAs and the InP are given as 1.00 eV (-5:08 eV) and 1.27 eV (-5:04 eV) respectivelly.6) The difference in the deformation potentials of the valence (conduction) band between the InAs and InP is very small. Therefore, the type-I excitondeformation potential interaction is almost the same as the type-II exciton-acoustic phonon deformation potential interaction.
