Combined ARPES and STM study of Pb/Au(111) Moiré structure: One overlayer, two symmetries

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 Moire structure with an approximate (5.77 x 5.77) R21.5 degrees. 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.
