a Simulated atomic arranging process and model of individual Rh nanocrystal. b HAADF-STEM image of Rh/GDY. c High-resolution HAADF-STEM image of a single Rh nanocrystal grown on GDY. The labelled squares indicate the areas magnified in the following observations. d Fast Fourier transform pattern of Rh/GDY from c. e HAADF-STEM image of Rh/GDY. f HAADF-STEM image of a (111) plane from area f marked in c. Terraced atomic layers represent a stepped surface. g HAADF-STEM image of a (111) plane with atomic kinks from area g marked in c. h–j HAADF-STEM images of the (111) plane, the intensity profile (inset of h) along the dotted line represents a stepped surface along the edge.
