Fig. 7: Pb-thickness dependence of the SO band splitting at the Pb/MoSe₂ interface.

Evolution of Δ_bs as a function of Pb-overlayer thickness through the indicated equivalent Г₁- and H-hotspots. The confidence interval widths for the Δ_bs values are indicated by vertical bars. Δ_bs saturates at a Pb thickness of 0.5 nm (about two full MLs).
