Numerical modeling of electric field distribution under the tip.
(a) Layout of the finite elements model : LiCGC slab (gray) with a hemispherical AlPO4 inclusion (red) and AFM tip (blue). The radius of the inclusion is 150 nm; tip apex radius is 50 nm. (b) Absolute values of electric field strength for different distances from the upper surface of the LiCGC slab along the line corresponding to the tip axes. The field strengths were calculated as functions of the distance δx between the tip axis and the center of the AlPO4 inclusion, as indicated in panel (a). The depths within the LiCGC slab are indicated in the figure legend. (c) and (d) Distribution of the electric potential in the xz-plane under the tip apex for (c) δx = 250 nm and (d) δx = 150 nm. The scale bar in (d) is common for (c) and (d).
