Figure 6. Temperature-dependent differential electron density mapping, (units: eÅ^-3); the color scheme quantifies relative changes in electron density at (0 0 z) between reference temperature T₁ (e.g., 327K) and comparison temperature T₂ (e.g., 335K); regions exhibiting red hues indicate local electron depletion, signifying outward electron migration; conversely, blue regions demonstrate electron accumulation, reflecting inward electron redistribution.
