Gap opening of image potential state on reconstructed Ir(001) surface
We have investigated the image potential states (IPSs) for the unreconstructed Ir(001)-(1×1) and the reconstructed Ir(001)-(5×1) surfaces by using two-photon photoemission spectroscopy. We reveal that the Ir(001)-(5×1) reconstructed surface covered by Xe adatoms exhibits a band gap of 100 meV, which...
