Angle-Resolved Photoemission and Band Structure of Copper
Abstract
The triangulation method, the appearance angle method and for the first time the surface emission method have been used for the determination of the electronic band structure of copper along the [001], [110] and [111] direction from ARPES spectra taken on the (110) and (111) faces. The experimentally derived bands are compared with first-principles calculations. For the bands up to energies of 20 eV above the Fermi energies it is found that Burdick's band calculation is in good agreement with experiment. Together with published normal emission data an almost complete experimental band structure below the Fermi energy is derived which clearly shows the spin-orbit splitting of the d-bands.
