FIG. 1.

Wettability pattern formation during cooling in the case of carboxyl acid showing (a) the beginning of the dewetting process and (b) the final array of sessile droplets. The inset shows an image of the reversed domain pattern.

FIG. 2.

Cross section of the PPLN sample (a) at equilibrium condition and (b) during the heating and cooling process. The net charge on the surface is illustrated. The arrows indicate the orientation of the spontaneous polarization.

FIG. 3.

(a) Simulation of the electric potential distribution generated by the pyroelectrically induced surface charge; (b) (top) solid-liquid interface tension profile; (bottom) section view of the oil topography.

Image of FIG. 4.
FIG. 4.

Two optical microscope images acquired during the cooling process in the case of the almond oil. The delay between the two frames was . The sessile droplets are formed only in correspondence of the reversed domains and not in regions lacking inverted domains (white circles).
