Fig. 2: Raman spectra of chemically treated MoS2 monolayers.

a Side views of Raman modes. b Raman spectra of pristine, H-TFSI-treated, and Li-TFSI-treated monolayer MoS2. The decomposed Lorentzian peak fitting of each spectrum is presented as a short, dashed line and the cumulative fitting is presented as a solid line. The positions of A1g and 2LA mode of pristine MoS2 as well as A2u mode of MoS2 with adatom (Li for example) are illustrated in each spectrum with a short black dashed line for direct comparison. The value of each peak position is also stated in the spectra.
