“…4 Recently, ARPES data recorded with photon energies of 32-33 eV seemed to show a different picture and have been interpreted in terms of an electronlike FS centered around the ⌫ point. [5][6][7] It has even been suggested that the ARPESderived FS depends on the photon energy used in the experiment. 6 This, of course, would constitute a revolution in our thinking about the normal-state FS's of the HTSC's and thus it is of utmost importance that this question be addressed quickly and clearly by a number of independent groups.…”

We address the question as to whether the topology of the normal-state Fermi surface of Bi 2 Sr 2 CaCu 2 O 8ϩ␦ -as seen in angle-resolved photoemission-depends on the photon energy used to measure it. High-resolution photoemission spectra and Fermi-surface maps from pristine and Pb-doped Bi 2 Sr 2 CaCu 2 O 8ϩ␦ are presented, recorded using both polarized and unpolarized radiation of differing energies. The data show clearly that no main band crosses the Fermi surface along the ⌫M Z direction in reciprocal space, even for a photon energy of 32 eV, thus ruling out the existence of a ⌫-centered, electronlike Fermi surface in this archetypal high-T C superconductor. The true topology of the normal-state Fermi surface remains that of holelike barrels centered at the X,Y points of the Brillouin zone.

“…The next important problem to be solved is whether the FS topology is photon-energy dependent or not, as presently discussed in Bi2212. [1][2][3][4][5][6][7][8][9][10][11][12]16 Figures 5͑a͒ and 5͑b͒ show ARPES spectra along the ͑0,0͒-͑,0͒ cut measured with 22and 28-eV photons, respectively. In contrast to the 22-eV spectra, the ARPES intensity at 28 eV is substantially suppressed around the ͑,0͒ point, as in Bi2212 around 33 eV, 3,4,7,9,11 suggesting an E F crossing of the band midway between ͑0, 0͒ and ͑,0͒ and as a result an electronlike FS centered at ͑0, 0͒.…”

We report temperature-dependent angle-resolved photoemission spectroscopy ͑ARPES͒ on superstructurefree Bi 1.80 Pb 0.38 Sr 2.01 CuO 6Ϫ␦ ͑overdope, T c Ͻ4 K͒ to study the topology of the Fermi surface. The temperature dependence of ARPES spectra unambiguously shows the existence of a dispersive band that crosses E F along the ͑,0͒-͑,͒ cut, indicating a holelike Fermi surface centered at ͑,͒. We also found that the spectral intensity is strongly affected by k-dependent matrix elements but the spectral function itself suffers no photonenergy dependence.

“…On the experimental side as well the ARPES studies of BISCO are far too numerous to be cited with any completeness, and we refer only to a few representative papers. [4][5][6][26][27][28][29][30][31][32][33][34][35] An outline of this article as is follows. The introductory remarks are followed in Section II by a consideration of formal matters; a few equations for the one-step model are presented (Subsection IIA), and the problem of computing the momentum matrix element in a general lattice is formulated (Subsection IIB).…”

We have carried out extensive simulations of the angle-resolved photoemission (ARPES) intensity in Bi2212 within the one-step and three-step type models using a first-principles band theory framework. The focus is on understanding the behavior of emissions from the antibonding and bonding bands arising from the CuO 2 bilayers around the M (π, 0) symmetry point. The specific issues addressed include: Dependencies of the photointensity on the energy and polarization of the incident light; character of the initial and final states involved as well as the spectrum of the relevant final states; and, changes in the spectral intensity as a function of the perpendicular component, k ⊥ , of the momentum of the photoelectron. Considerable insight into the nature of individual transitions is adduced by examining the momentum matrix element for bulk transitions within the solid and by further decomposing this matrix element into contributions from various atomic sites and angular momentum channels. These results indicate that, via remarkable interference effects, the ARPES matrix element can in particular cases help zoom in on the properties of electrons excited from specific sites and/or angular momentum channels even in a complex material.
