WebWe address this point in this paper, showing that freshly mechanically exfoliated MoS 2single layers have a TM-AFM measured distance from the substrate that varies from 2.3 to 3.0nm, and we discuss these anomalously large stacking from the substrate. 1.1.4. Raman spectroscopy layer number identification WebLiquid-phase exfoliation is likely to be feasible for practical fabrication of few-layer MoS2 nanosheets in large quantities. However, this method generally involves the organic solvents with high boiling point; new strategy using low-boiling-point solvents to obtain high MoS2 concentration is still highly required.
