a Optical images of a bar-shaped MoS2 crystal before and after bending. b Scanning electron microscopy (SEM) images of an Ag bar before and after bending. Black ink is marked on sample’s top surface to help to fix the position. c SEM image of area 1 in a. d, Inverse Fourier transform of the dark-field scanning transmission electron microscopy (IFT-DF-STEM) image of area 2 in a. e Crystal structure of 2H-MoS2. f Generalized stacking fault energy (GSFE) surface of MoS2 (001) plane. g GSFE surface of MoS2 (\(1\bar{1}0\)) plane. h The integrated crystal orbital Hamilton population (-ICOHP) analysis of the interlayer chemical interactions between the slip planes for (001)1/3[210]+1/3[\(1\bar{1}0\)] slip system shown in f. i -ICOHP analysis of the chemical interactions between the slip planes for (\(1\bar{1}0\))[001] slip system shown in g.
