Fig. 7. Optical images of (a) as-grown, and (b) S-intercalated hBN grains, on an Au substrate. KPFM potential images of hBN grains (c) before and (d) after S-intercalation. (e) Potential profiles along the white-dashed boxes in (c) and (d).(f) AFM topography image and (g) Raman spectrum respectively, of monolayer hBN grains after their transfer onto a SiO2/Si substrate. The inset of (f) shows a height profile extracted from the white-dashed line.
