Figure 2. Characterization of the exfoliated LMs.

(a,f) Typical absorption spectra of the exfoliated graphene (a) with a peak absorbance at 260 nm and the exfoliated MoS₂ (f) with absorbance peaks at 657, 602 and 385 nm. (b,g) AFM images and section height profiles of the exfoliated graphene (b) and MoS₂ (g). (c,h) Sheet thickness distribution of exfoliated graphene (c) and exfoliated MoS₂ (h). (d,i) TEM images and ED patterns of few layer graphene (d) and MoS₂ (i). (e,j) HRTEM images of the exfoliated graphene (e) with a lattice spacing of 0.265 nm and MoS₂ (j) with a lattice spacing of 0.317 nm. Scale bars, 200 nm (b,g), 500 nm (d), 100 nm (i), 1 nm (e,j).
