The incommensurate composite structures consists of misfit layer structures, intergrowth compounds, Vernier structures and chimney-ladder structures [1 - 3]. For instance, the general formula A1-pCr2X4-p (A = Ba, Sr, Eu, Pb, X = S, Se) [1 - 3] represents an unusual average structure formed by the intergrowth of three different substructures that are mutually incommensurate along one direction.
