Some new organic-inorganic hybrid semiconductors based on metal halide units: structural, optical and related properties

Abstract

The structural, optical and related properties of organic–inorganic hybrid semiconductors based on the organic molecules (cations) CH3NH3, H3N(CH2)6NH3, C6H5CH2NH3, CH3C6H4CH2NH3, CH3OC6H4CH2CH2NH3, (H2N)2CS(CH2)4SC(NH2)2, H3NCH2CH2OCH2CH2NH3, C6H5CH2CH2SC(NH2)2, C10H21SC(NH2)2, O2NC6H4CH2SC(NH2)2, 1-naphthylmethylammonium C10H7CH2NH3, 9-anthrylmethylammonium C14H9CH2NH3 and 1-pyrenylmethylammonium C16H9CH2NH3 and the inorganic units MXn (anions) (M≡Bi, Sb, Sn, Pb, Cu, Ag; X≡I, Br, Cl) are described. There is evidence that the position, intensity and shape of the excitonic bands depend on the order/disorder of the inorganic component and on the electronic interaction between organic and inorganic components.
