8 Claims

1. A nanosheet having ferroelectric-like properties, comprising two or more two-dimensional layers, and represented by Formula 1 below:

M_x−mA_yB_z

wherein M is at least one of Group I or Group II elements, A is at least one of Group III elements, B is at least one of Group V elements, x, y, and z are positive numbers which are determined according to stoichiometric ratios to ensure charge balance when m is 0, and wherein the m satisfies 0<m<x.
