Figure 6. Interface-scale engineering of heterogeneous composite ceramics for enhanced dielectric and ESP. (A) Schematic of a multilayer sandwich structure combining RFE and RAFE components. The accompanying plot shows the ε_r as a function of applied DC electric field, with microstructural insets illustrating the evolution of domain structures under different field strengths.
