Energy distribution curves (EDCs) near Fermi level (EF). EDCs obtained by integration of the corresponding angle-resolved ultraviolet photoelectron spectra around the K point in a narrow interval (1.08–1.36 Å−1), of a MoS2/sapphire, b MoS2/highly oriented pyrolytic graphite (HOPG), and c MoS2/Au with (violet) and without (green) adsorbed F6TCNNQ. The numbers inside the plots correspond to the MoS2 valence band onset, given in electron volts (eV)
