Electronic Spectra and Their Relation to the (pi,pi) Collective Mode in High-Tc Superconductors

J. C. Campuzano, H. Ding, M. R. Norman +15

Photoemission spectra of Bi2Sr2CaCu2O8 reveal that the high energy feature near (pi,0), the "hump", scales with the superconducting gap and persists above Tc in the pseudogap phase…
