Abstract: The structural and electronic properties of a Pb monolayer (ML) grown on Au(111) are investigated by scanning tunneling microscopy (STM) and angle resolved photoelectron spectroscopy (ARPES). We find an incommensurate Moir\'e structure with an approximate $(5.77\ifmmode\times\else\texttimes\fi{}5.77)$ R21.5${}^{\ensuremath{\circ}}$ unit cell, and two rotational domains. We observe three Pb-derived bands of $p$ orbital character. The symmetry properties and sharpness of their Fermi surfaces are remarkably different. They reflect the different degrees of hybridization of these bands with the Au(111) bulk continuum.
