Figure 2 | Photo-generated carrier transport properties on the surface of 2D perovskite materials.

Caption

(a) Representative 3D color-coded maps illustrating the evolution of photo-induced electron transport in the n=3 2D perovskite sample. (b) Schematic structures of 2D halide perovskite ((BA)2(MA)n-1PbnI3n+1) with varying inorganic layer thicknesses (n=1,2,3). (c) Charge transmission eigenstates at the Г point at the Fermi level of the three types of samples. The intensity of the color indicates the distribution of transmission channels filled within the sample from the surface to the bulk. (d) Estimated surface carrier diffusion coefficients for perovskite layers with n ranging from 1 to 3.
