Electronic properties of P[103]&P[−103] domain structures of MAPbI3. a–c report the layer-resolved local density of states for the 10 × 1 × 1, 18 × 1 × 1, and 22 × 1 × 1 configurations, respectively, when going from the T-T (top figure) to H-H (bottom figure) layers. d shows the energy band structure for the n = 22 case. Note that the numbers “−5”,.. “0” indicated in a correspond to the layers shown in Fig. 1, and a similar nomenclature is used for b and c. The vertical dashed lines in a–c represent the energy of the Fermi level (which is chosen to be the zero in energy)
