| Abstract: From a detailed study, including polarization dependence, of the normal state angle-resolved photoemission spectra for Bi2Sr2CaCu2O8, We find only one CuO2 band related feature. All other spectral features can be ascribed either to unklapps from the superlattice or to ''shadow bands.'' Even though the dispersion of the peaks looks like band theory, the line shape is anomalously broad and no evidence is found for bilayer splitting. We argue that the ''dip feature'' in the spectrum below T-c arises not from bilayer splitting, but rather from many-body effects. |
