Figure 2. Minimizing similarity metrics for the analysis of Charge Density Variations in Ti3C2O0.24(OH)1.28F0.48. The depicted cyan and yellow areas signify zones of reduced and enhanced charge, respectively. An insert illustrates a two-dimensional cross-section of the charge density variance as seen from the (100) orientation, setting the isovalue limits from -0.03 to +0.03 electrons per cubic angstrom. A specific area marked in red within the insert accentuates a locally generated dipole on the surface. (A) Ordered Termination Surface of Ti3C2O0.24(OH)1.28F0.48. (B) Random Termination Surfaces of Ti3C2O0.24(OH)1.28F0.48[46].
