Fig. 3: Structural characterizations of the interfaces between MoS2 monolayer and Au (001) surface of NPG.

a, c, e Raw HAADF-STEM images viewed from the [110]Au (a), [100]Au (c) and [0\(\bar 1\)0] Au (e) directions. Scale bar, 0.5 nm. b, d, f Filtered atomic-resolution HAADF-STEM images with false color viewed from the [110]Au (b), [100]Au (c) and [0\(\bar 1\)0] Au (e) directions. Color variation from black to blue and then to yellow corresponds to the intensity from low to high. The magenta and green lines are intensity profiles measured along the Au topmost layer and sublayer following the corresponding arrows in (b, d) and (f), respectively. Scale bar, 0.5 nm.
