Abstract:
A two-dimensional perovskite forming material with an ammonium halide group disposed on its surface can achieve a high carrier mobility. Preferably, the two-dimensional perovskite forming material includes a monolayer that has such an ammonium halide group at a terminal of its molecular structure, and the ammonium halide group in the monolayer is disposed in an ordered fashion on the surface of the material.

Claim (Index 27):
The stacked structure according to  claim 21 , wherein the two-dimensional perovskite layer comprises a perovskite-type compound represented by any one of the general formulas (2) to (4) below:\n A 2 BX 4 \u2003\u2003(2) wherein A represents an organic cation, B represents a divalent metal ion, and X represents a halogen ion, and the two instances of A, or the four instances of X, may be the same as each other or not,\n A 2 2 A 1 n\u22121 B n X 3n+1 \u2003\u2003(3) \n wherein A 1  represents an organic cation, A 2  represents an organic cation with a carbon number greater than that of A 1 , B represents a divalent metal ion, X represents a halogen ion, n represents an integer from 1 to 100, the two instances of A 2 , or the plural instances of X, may be the same as each other or not, and when n is 3 or more, the plural instances of A 1  may be the same as each other or not,\n A 2 2 A 1 m B m X 3m+2 \u2003\u2003(4) \n wherein A 1  represents an organic cation, A 2  represents an organic cation with a carbon number greater than that of A 1 , B represents a divalent metal ion, X represents a halogen ion, m represents an integer from 1 to 100, the two instances of A 2 , or the plural instances of X, may be the same as each other or not, and when m is 2 or more, the plural instances of A 1  may be the same as each other or not.
