Calculated band structures and impact of electron transmission eigenstates on transport properties. a–c Electronic band structures of 2D perovskites corresponding to n = 1, 2, and 3, respectively, derived from calculations performed using GGA/PBE+vdW method. d The effective mass of electrons and holes in the corresponding 2D perovskites. e–g Transmission eigenstates at the Г point at the Fermi level of the three types of samples, the top side represents the top surface of the sample layers, while the bottom side faces toward the bulk. The intensity of the color indicates the distribution of transmission channels filled within the sample from the surface to the bulk. The isovalue of the transmission eigenstate is 0.15 (Å3·eV)-1/2
