a Schematic illustration of cyclic heating–cooling–induced repeated carbon segregation. b Optical images of graphite films with various thicknesses on Ni and Co foils. c WLI maps at the graphite film edges with thicknesses ranging from 1 to 5 μm. d Cross-sectional height profiles extracted from WLI maps of (c). e, f Scatter plot and linear fitting of graphite thickness as a function of cycle number on Ni foil (e) and Co (f) foil, respectively. The error bars represent the standard deviation of repeated experiments.
