Figure 2. Charge distribution and electrical double layer characteristics of surface-terminated Mo₂CT_x (T = F, Cl, Br, I) MXenes. (A) Quantum charge curves corresponding to Mo₂CT_x; (B) Net charge distribution of electrode and electrolyte along the z direction, where the position of C layer is at z = 0 Å. The electrode applied potential is 1 V vs. PZC; (C) EDL charge curves corresponding to Mo₂CT_x; (D) Total charge curves corresponding to Mo₂CT_x; (E-H) Iso-surface (0.0005 e/ų) of differential electron densities between charged (1 V vs. PZC) and uncharged Mo₂CT_x. PZC: point of zero charge; EDL: electric double-layer.
