The topographic structures of MBE-grown MoSe2 films. a Large-scale STM image of 0.85 ML MoSe2 on HOPG (size: 100 × 80 nm2, VS = −1.4 V). b Statistical analysis of the triangle MoSe2 domain size. The red line is the fitting distribution curve. c A close-up STM image of the inversion domain boundary network (size: 30 × 30 nm2, VS = −1.3 V). d The corresponding nc-AFM image recorded in the same area as panel c. e A high-resolution nc-AFM image (size: 5 × 5 nm2) shows a typical wagon-wheel pattern. The Se atoms appear as bright spots in the frequency shift image. Here, the orange and blue balls represent the Se and Mo atom, respectively. f An atomistic model corresponding to the experimental structure shown in e. The red dashed line highlights the Se-edge of MoSe2 triangle domains
