Abstract
We studied the geometric and local electronic structure of a Se-adsorbed Au(111) surface. The reconstructed herringbone structure disappeared and the Au(111) surface states were attenuated with Se adsorption on the Au(111) surface, as explained by density functional theory calculations. Electron interference patterns were observed on the exposed Au (111) surface due to electron scattering by potential barriers formed by Se adsorbates. A strong bound state from the Se p-orbital on top of the Se clusters with quantum confinement effects were observed using scanning tunneling microscopy and spectroscopy. © 2019 Published by Elsevier B.V.
