Fig. shows the results of the fitting procedure applied to the absorbance spectra in Fig. . The model captures all potential-dependent features of the A-exciton region, specifically how the A 0 and A -peak intensities, positions, and widths change with applied potential. A key point of Fig. is we obtain a single 𝜀 F value that best describes each measured spectrum. Minor disagreement between the MND model and experimental data, such as the high energy tail region, is likely because the MND model only considers the pristine ML-MoS2 sample in vacuum and does not consider the possible screening effects from the substrate and liquid electrolyte. Disagreement between the theory and experiment may also be due to non-Gaussian sources of broadening that we do not consider, as well as the simple background subtraction method that does not accurately remove contributions from the B exciton and B trion, which the model does not consider.
