FIG. 1.

Polarization distribution of freestanding 2D square-shaped nanoparticles under ideal open-circuit boundary conditions with no surface charge compensations. Arrows represent the in-plane polarization vectors. (a) Single-vertex structure in a nanoparticle. (b) Single-vertex structure with a four 90° domain wall pattern in a nanoparticle.

FIG. 2.

The relations between the existence dimensional range for single-vertex structures and the square root of the normalized exchange energy parameter , where is the characteristic quantity used in Ref. 10. The dashed line represents the 180° domain wall thickness evaluated according to the scaling law. It shows that the existence range follows the same scaling law and the lower bound is comparably close to the domain wall thickness.

Image of FIG. 3.
FIG. 3.

Polarization distribution of freestanding 2D nanoparticles under ideal open-circuit boundary conditions with no surface charge compensations. Arrows represent the in-plane polarization vectors. (a) Double-vertex structure obtained from a nanoparticle with initially randomly distributed polarizations. (b) “Squeezed” single-vertex structure obtained by initially distributing the polarizations in a pattern with a little favor to circular flow around the geometric center.
