Extended Data Fig. 1: Ab initio lattice relaxation results for twisted AA-stacked SnSe2 and ZrS2 at θ = 3.89°.

a–c, For twisted SnSe2: interlayer distance (ILD) (a); intralayer atom displacements in the bottom (b) and top (c) layers. d–f, Same as a–c but for twisted ZrS2. The definitions of the C3z-symmetric local regions labelled by AAi (for 1 ≤ i ≤ 3) are given in Supplementary Information Section III.
