(a) Top-view TEM image, (b–e) elemental mapping images, (f) XPS spectra, (h,i) AFM images, side-view TEM image (m) and atomic-resolution HAADF-STEM image (n), and (o–s) the corresponding EELS elemental maps of BOC-MS. Scale bar, 500 nm, 1 μm, 500 nm, 10 nm and 5 Å, in a,h,i,m,n, respectively. (g) S K-edge XANES spectra of BOC-MS, 1L-MS and bulk MS. (j) Height profiles along the lines in i. (k) Comparison of the average thicknesses of 1L-BOC and 1L-MS in BOC-MS. The error bars in k represent the s.d. of over 100 independent AFM measurements. (l) The theoretical thicknesses of MoS2 and Bi12O17Cl2 monolayers.
