Here, we report a cyclic segregation/dissolution strategy for growing uniform AB-BLG single crystal on the single-crystal Cu/Ni(111) foil. The positive correlation between the carbon solubility in solid metals and temperature was used to realize the reversible growth and etching of graphene for tailoring its structural uniformity. Thus-prepared single-crystal BLG film shows the high bilayer coverage and AB-stacking with the electrical property comparable to that of exfoliated ones.
