From: Heterogeneous integration of single-crystalline complex-oxide membranes

Extended Data Fig. 1

a, Illustration of the simulated structure. b, The potential fluctuation through graphene as a function of monolayer (1ML) and bilayer (2ML) graphene thickness d. The inset shows the potential fluctuation map on the surface of graphene-coated STO substrates for monolayer graphene (left) and bilayer graphene (right). c, The potential fluctuation map (colour scale) with three monolayers of graphene on top of the STO surface. d, Cross-sectional potential profile along the red line shown in c.
