Abstract

Organic-inorganic quantum well materials, (C_nH _2n+1NH₃)₂PbX₄ (X=I, Br), form self-organized two-dimensional (2D) systems, where inorganic semiconductor well layers are sandwiched by organic barrier layers. Owing to strong quantum confinement and dielectric enhancement effect, ideal 2D-Wannier exciton exists in these materials [1]. It has been founded that the binding energies of the exciton (E_ex) and the biexciton (E_bi) are extremely large (E_ex ∼360meV and E_bi ∼40meV for (C ₆H₁₃NH₃)₂PbI₄ [1], E _ex ∼480meV and E_bi ∼60meV for (C₄H ₉NH₃)₂PbBr₄ [2]), which are the largest values ever reported. Thanks to the large binding energies, these materials are quite suitable to investigate various properties of 2D-exciton system. In this study, we have investigated the fine structure of the excitons in (C₆H₁₃NH₃)₂PbI₄and (C₄H₉NH₃)₂PbBr₄ using photo-luminescence (PL) measurement under magnetic field and spin-flip Raman scattering (SFRS) measurement.
