Abstract
The electronic structure of monatomic Cu and Co wires grown by step decoration of the vicinal Pt(997) surface has been investigated by angle-resolved photoemission with synchrotron radiation. Sensitivity to the small amount (≈0.1 monolayer) of deposited material that forms the one-dimensional wires could be achieved at photon energies close to the Pt Cooper minimum, where the photoemission cross section of the substrate valence band is strongly reduced. A single photoemission feature is associated with the emission from the Cu monatomic wire. A double-peaked structure is instead observed for Co wires, suggesting the presence of a one-dimensional exchange-split band and of local magnetic moments.
