a Atomic-scale HAADF-STEM image of the boundary of [021]OD and [021]RD domains. The purple rectangles highlight the Te-sublattice in the original domain ([021]OD) and the rotation domain ([021]RD), illustrating the anisotropic deformation of the Te-sublattice, referring to elongation along the tensile axis (F[02\(\bar{1}\)]) direction and compression along the transverse direction (F[201]) direction. b Atomic model diagram of the domain boundary. c Strain maps of the boundary of [021]OD and [021]RD domains. The reference region is selected from the unstrained area (top-left corner, as outlined by the red rectangle) of the [021]OD to ensure computational accuracy. d Strain profiles across the domain boundary. Line profiles of the strain components (εₓₓ, εᵧᵧ, εₓᵧ) measured along the path from [021]OD to [021]RD in c.
