Spatial confinement, self-polarization and exciton–phohon interaction effect on the location of exciton line in lead iodide nanofilms

Spatial confinement, self-polarization and exciton–phohon interaction effect on the location of exciton line in lead iodide nanofilms

Theoretical investigation of the spatial confinement, self-polarization and exciton–phonon interaction influence on the exciton state in plane double nanoheterostructure (nanofilm)–lead iodide in polymeric matrix is performed within the effective mass approximation for the electron and dielectric co...
