Model calculation of CEDL (a) Schematic representation of the charge distribution -qi in FLG, which shields the electric field. (b) Calculated capacitances as a function of n. Geometrical capacitance Cg, quantum capacitance Cq, and EDL capacitance CEDL are indicated by green, purple, and black lines, respectively. Details of the calculation can be found in the main text and Supplementary Information. We find that the CEDL is limited by Cq for n < 4 and by Cg for n > 4.
