Fig. 5: Evolution of the core-level and VB spectra upon deposition of the amorphous Pb overlayer.

a XPS overview spectra at hv = 1000 eV showing the Mo 3d and Pb 4f core levels depending on the cumulative Pb thickness. b In-plane ARPES images along the Г1K and AH directions of the 3D-BZ for a Pb thickness of 0.25 nm, and c these images in red colorscale overlaid with the bands of bare MoSe2 (blue). Besides an increase of the incoherent background, broadening of the spectral peaks and their marginal k-dependent energy shifts, the Pb overlayer does not much affect the MoSe2 electronic states.
