Phys. Rev. B 72, 195417 (2005) [5 pages]Atomic-orbital analysis of the Cu Fermi surface by two-dimensional photoelectron spectroscopyReceived 19 October 2004; revised 23 May 2005; published 18 November 2005 A method for atomic-orbital orientation determination at each k point has been developed. The three-dimensional Cu Fermi surface (FS) structure was measured and visualized by stacking a series of photoelectron intensity angular distribution (PIAD) at different photon energies. PIADs from the Cu(001) surface were obtained using a display-type analyzer and linearly polarized synchrotron radiation. The atomic orbitals composing the FS were determined to be mainly 4p orbitals with their axes pointing outward. Atomic orbital orientations at different k coordinates on FS as well as the FS cross-section structures were revealed directly from experiment and were confirmed by ab initio calculation. © 2005 The American Physical Society URL:
