Fig. 2. (a) Schematic diagram of SKPM applied to MoS₂/hBN/MLG heterostructure. (b) Optical image of MoS₂/hBN/MLG heterostructure (scale bar, 10 µm). Inset: enlarged image of a bubble on MoS₂ surface (scale bar, 2 µm). (c) Topography (left) and surface potential (right) images of bubble shown in inset of panel b (scale bars, 0.5 µm). (d) Height (black line) and △V_CPD (red line) profiles following dashed lines for topography and surface potential image shown in panel c.
