Multidimensional imaging on ${\text{MoS}}_2$/graphene. (a) ${\text{MoS}}_2$ Raman spectrum, fitted with E1 and A-bands, (inset) A-band intensity map; (b) Raman spectra for graphene off/on ${\text{MoS}}_2$ island, fitted by G (orange), ${\text{D}}^{\prime }$ (pink) and 2D (green) bands, (inset) Raman map of 2D-amplitude showing the island location; (c) KPFM (a) KPFM image; (d—f) calculated graphene doping, hydrostatic and shear strain maps, overlaid with scanning electron microscopy image; (g, h) doping and strain for ${\text{MoS}}_2$ layer overlaid with SEM image; (i) sSNOM phase image of the same area.
