Essay

Within the effective mass approximation for electronic and dielectric continuum model - for the phonon system, using method of the Green's function theory there were studied exciton interaction with optical phonons in layered ionic semiconductor - indium selenide and lead di-iodide nanofilm, placed in a dielectric medium - glass or polymer E-MAA. Taking into account the effects of spatial confinement, self-poliarization and interaction with phonons was calculated electrons, holes and excitons energies and spectral dependence of the form function of the exciton absorption band in these environments, analyzed their temperature changes.
