Photoemission footprints of extrinsic plasmarons
arXiv:1506.07714 · doi:10.1103/PhysRevB.92.205421
Abstract
A prediction how to experimentally distinguish excitations of extrinsic plasmarons from intrinsic plasmarons is presented. In surface systems where excitations of acoustic surface plasmons is possible it is shown that the photo-electron yield in normal photoemission should decay according to an inverse square root dependence with respect to the photon energy. A computational analysis of the system p(2x2)-K/Graphite confirms this prediction.
