Patent ID: 8471290

Claim:
A crystalline inorganic-organic hybrid structure comprising a plurality of layers of a repeating unit, said repeating unit comprising a first organic ligand layer, a second organic ligand layer, and a two-dimensional semiconducting inorganic double layer having two opposing surfaces therebetween, wherein: the two-dimensional semiconducting inorganic double layer comprises two single atom thick layers of a II-VI chalcogenide compound of formula M 2-x Mn x X j Y 2-j , wherein M is a II-VI semiconductor cationic species, X and Y are two different chalcogens, j is a number greater than 0 but smaller than 2, and x is a number in the range from 0 to about 1.0, inclusive; and the first organic ligand layer and the second organic ligand layer are attached to the two opposing surfaces of the two-dimensional semiconducting inorganic double layer through a covalent bond or a coordinate covalent bond between said compounds of said organic ligand layers and the metal cation species of the II-VI chalcogenide compounds, so that the semiconducting inorganic double layer is directed by the compounds of the two opposing organic layers to form ordered crystal lattices.
