Abstract

In this work electronic structures and optical properties of organic-inorganic exciton and polaritons in two-dimensional heterostructures combining both organic and semiconductor materials are studied. In those systems, Wannier-Frenkel hybrid exciton has unique and interesting properties that can improve the efficiency of optical materials. When an organic-semiconductor combined heterostructure is illuminated by high-intensity electromagnetic radiation with the frequency of the photons at or near the resonance frequency of the Wannier-Frenkel exciton, we obtain a macroscopically occupied system of hybrid polaritons. We will theoretically determine electronic structure, energy and dispersion relation of the hybrid excitons and polaritons. By analyzing the parameters of the systems and the interactions between the Wannier and Frenkel excitons and the photons, we then discuss the conditions for hybridization.
