▎ 摘　　要

We study a family of globally smooth, spatially varying, two-dimensional stacking textures in bilayer graphene. We find that the strain-minimizing stacking patterns connecting inequivalent ground states with local AB and BA interlayer registries are two-dimensional twisted textures of an interlayer displacement field. We construct and display these topological stacking textures for bilayer graphene, examine their interactions, and develop the composition rules that allow us to represent other more complex stacking textures, including globally twisted graphenes and extended one-dimensional domain walls.
