Abstract
We study the Fermi surface of Bi2Sr2CaCu2O8 using angle resolved photoemission
spectroscopy (ARPES) with a momentum resolution of ~0.01 of the Brillouin
zone. We show that, contrary to recent suggestions, the ARPES derived
Fermi surface is a large hole barrel centered at (π,π), independent
of the incident photon energy. We caution that the photon energy
and k dependence of the matrix elements, if not properly accounted
for, can lead to misinterpretation of ARPES intensities.
