Inelastic electron-electron scattering for surface states on Cu(110) and Ag(110)

Many-body electron-electron scattering contribution to the decay rate of electron and hole excitations on the (110) surface of copper and silver is calculated within GW approximation for electron self-energy. The band structure is described using a two-dimensional model pseudopotential, which precis...

Sumario:Many-body electron-electron scattering contribution to the decay rate of electron and hole excitations on the (110) surface of copper and silver is calculated within GW approximation for electron self-energy. The band structure is described using a two-dimensional model pseudopotential, which precisely reproduces the surface electronic structure at the Ȳ point. Combined with the previously calculated electron-phonon contribution, our result for the occupied state on Cu(110) agrees well with the available photoemission data. © 2011 American Physical Society.
