(a) NR reflectivity curves for contrast matched 2EHL + 5% P-BOB at different applied potentials. The curves are offset in the Y-axis for clarity. The symbols represent experimental data, whilst the solid lines are best-fits to the data. Inset: Asymmetry plot highlighting the changes in the non-zero potential NR curves with respect to the 0 V curve. (b) SLD profiles obtained from the best fits to the NR data (z = 0 at the gold/solution interface).
