Abstract

A large class of new layered semiconductors - perovskite lead iodide compounds - is of great interest because of possible optoelectronic applications due to pronounced excitonic effects. It has been predicted earlier that excitons in these structures should be enhanced due to the so called "dielectric confinement" arising from large difference of dielectric constants of adjoining layers. In the present work we calculate the energies, the wave functions, diamagnetic coefficient of excitons in these naturally grown superlattices with allowance for the image potential and the superlattice structure of the compounds. The fitting of our theory to the experiments makes it possible to evaluate the reduced mass of excitons in these compounds.
