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.
