Figure 7. Interface polarization and local electric field modulation in brick-and-mortar ceramic structures. (A) Schematic of a brick-and-mortar ceramic architecture, illustrating structural heterogeneity; (B) Maxwell-Wagner two-layer condenser model describing interface polarization and its influence on local electric fields. (C and D) Simulated electric field distributions across the sample as a function of potential difference (Δ) under two scenarios: (C) when the resistance of layer 1 greatly exceeds that of layer 2 (R₁ ≫ R₂), and (D) when the resistances are comparable (R₁ ≈ R₂).
