a Large-area STM image (VTip = –0.61 V, ITip = 3.55 nA) of the monolayer MoS2 film on the Au(223) facet with Au(111) terrace. b Magnified STM image (–0.1 V, 30.77 nA) of the green square region in (a), presenting the perfect alignment of MoS2 lattice direction with moiré row direction, as denoted by green and yellow arrows, respectively. Inset: corresponding 2D-FFT pattern. c, d Representative atomically resolved STM images of the moiré pattern for MoS2/Au(111), presenting a fixed period of ∼3.21 ± 0.10 nm (marked by white rhombus; −0.10 V, 40.95 nA; −0.1 V, 32.79 nA). e Photograph and corresponding OM image of a 1-inch single-crystal MoS2 film transferred on SiO2/Si. f Raman mapping on the A1g peak intensity for the monolayer MoS2 single crystal showing a uniform color contrast. g PL mapping on the A exciton intensity of the monolayer film. h SHG mapping of the monolayer MoS2 single crystal.
