(a) PDOS of MAPbI3 materials and the inset represents the schematic diagram for the coupling interaction near band edges. (b) Energy shifts of VBM and CBM caused by the external strain with the presence and absence of rotation of MA molecule, respectively. (c,d) Are PDOS of MAPbI3 without and with the distortion of PbI6 octahedra, respectively. Insets in (c,d) illustrate the standard PbI6 octahedron and tilting PbI6 octahedron, respectively.
