From: Substrate-induced modulation of transient optical response of large-area monolayer MoS2
XPS spectra of MoS2 ML on (a) sapphire (as-grown), (b) sapphire (transferred), (c) quartz (transferred), (d) Si/SiO2 (transferred) substrates with component peak-fitting. Red solid lines represent the overall fit to experimental data (black dots). The colour regions under the overall fitted curve show contributions of different states.
