Fig.1 Intrinsic stacking sequence of 2H and 3R β-In₂Se₃. (a) Atomic-scale HAADF-STEM image of the 2H β-In₂Se₃ with the stacking sequence of $\bar{A} C \bar{A} C$ viewing at [ $\bar{1}$ 2 $\bar{1}$ 0] zone axis. (b) Atomic-scale HAADF-STEM image of the 3R β-In₂Se₃with the stacking sequence of $C B A C$ viewing at [ $\bar{2}$ 1 1 0] zone axis
