  This work aims to explore the intrinsic properties of two-dimensional(2D)-layered perovskites,(PEA)2PbI4(N)and Cs2PbI4(N),and demonstrating how their structures and properties vary with N.The results reveal that both(PEA)2PbI4(N)and Cs2PbI4(N)are direct bandgap semiconductors,their band/optical gaps and exciton-binding energies vary linearly with 1/N at N ≥ 3,and the effective masses slowly vary with N.
