Abstract
We measured the normal state Fermi surface of a Pb0.42Bi1.73Sr1.94Ca1. 3Cu1.92O8+x(001) single crystal using angle resolved photoemission. Ou r experimental approach allows us to see the full topology and symmetr y of this essentially two-dimensional system. The geometrical structur e is probed using x-ray photoelectron diffraction and transmission ele ctron microscopy. Structural effects on Fermi surface features are dis cussed. Moreover, a series of energy distribution curves is measured f or an azimuthal scan of emission angles and a quantitative analysis of the bands crossing the Fermi level is given.
