Fig. 3

a XPS spectra of Ag 3d core levels before (lower panel) and after growth of P chains (upper panel). b P 2p core-level spectrum, presenting only one doublet (red curve). (Black dots present the data; black curve presents the best fit.) c The HR-ARPES were recorded at photon energy of 60 eV along K–Γ–M directions after deposition of P chains on Ag(111) surface. d STS dI/dV spectra acquired on the P chains, demonstrating the semiconducting character of P chains. The curve is an average of 40 individual spectra.
