a Schematic illustration of the liquid exfoliation process of bulk MoS2 crystal. b UV-vis absorption spectrum of MoS2-IPA solution. Inset is the photograph of the MoS2-IPA dispersion. c Raman spectra of exfoliated MoS2 nanosheets. Raman signal of bulk MoS2 crystal is also presented for comparison. d Atomic force microscopy statistics indicating the flake thickness distribution of the MoS2 dispersions. e The lateral flake size distribution of three types of MoS2 dispersions. To be noted, arb. units refer to arbitrary units.
