The free-electron-like state observed in a scanning tunnelling spectroscopy study of a chiral p(2×4) monolayer of glycinate ions on the copper (100) surface [Kanazawa K et al 2007 J. Am. Chem. Soc. 129 740] is shown from density functional theory calculations to originate from a copper Shockley surface state at the surface Brillouin zone boundary of the clean surface with highly anisotropic dispersion. The presence of the glycinate ions on the surface causes a dramatically enhanced tunnelling into this surface state that is otherwise not observed in tunnelling on the bare surface.
