On page A6 Figure 10. should be
Figure 10. Potential (ϕ) profiles along the z-axis at varying excess charge densities as specified (in μC/cm2). To facilitate comparisons, the ϕ near the negative graphene electrode is shown on a negative scale, i.e., the shown ϕ = −ϕ. In all cases, ϕ = 0 for the bulk electrolyte and each electrode is located at z = 0.
On page A7 Figure 12. should be
Figure 12. Comparison of pristine graphene's density of states (DOS) from theory (Ref. 73), experiment (Ref. 78), and DFT.
On page A8 Figure 13. should be
Figure 13. Calculated quantum capacitance (CQ) of pristine graphene based on the DOS (inset). E = 0 eV indicates the position of the Fermi level.
On page A8, left column, the second complete sentence in the first paragraph should be
As shown in Fig. 13, the calculated CQ (300 K) for the pristine graphene based on the DOS from DFT exhibits a U-shaped curve, contrary to CD, with a minimum around 0.73 μF/cm2; note that CQ = 0 when φG = 0 due to the thermal broadening of the electron energy distribution, and as expected the CQ curve is symmetric about φG = 0.
On page A8 Figure 15. should be
Figure 15. Total interfacial capacitance (CT) as a function of applied potential (ϕa). The inset shows corresponding EDL capacitance (CD) and quantum capacitance (CQ).
