Fig. 1: Schematic of complex polarization framework and unusual Bloch-type domain walls in t-BN.
From: Edge polarization topology integrated with sliding ferroelectricity in Moiré system
A Top view of the relaxed atomic structure of t-BN. B Perspective view of moiré structure. C Top view of IP polarization with clockwise and counterclockwise like merons and anti-merons. OOP polarization at the edge is displayed in the form of blue and red colors. The color bar represents the direction of OOP polarization. D Unusual Bloch-type domain walls with down-up-down-up polarization transitions.
