The surface atomic and electronic structure after deposition of one-third of a monolayer Te on Cu(111) was determined using a combination of low-energy electron diffraction (LEED), scanning tunneling microscopy and spectroscopy (STM/STS), angle-resolved single and two-photon photoelectron spectroscopy (ARPES /AR-2PPE), and density functional theory (DFT) calculations. Contrary to the current state in literature, Te does not create a two-dimensional surface alloy but forms
Cu2Te2 adsorbate chains in a (2√3×√3)R30∘ superstructure. We establish this by a high-precision LEED-IV structural analysis with Pendry R factor of R=0.099 and corroborating DFT and STM results. The electronic structure of the surface phase is dominated by an anisotropic downward dispersing state at the Fermi energy EF and a more isotropic upward dispersing unoccupied state at E−EF=+1.43eV
. Both states coexist with bulk states of the projected band structure, and are therefore surface resonances.
