Angle-resolved photoemission spectroscopy of band tails in lightly doped cuprates
journal contribution
posted on 2009-02-19, 13:22 authored by A.S. Alexandrov, Kimberley ReynoldsWe amend ab initio strongly correlated band structures by taking into account the band-tailing phenomenon
in doped charge-transfer Mott-Hubbard insulators. We show that the photoemission from band tails accounts
for sharp “quasiparticle” peaks, rapid loss of their intensities in some directions of the Brillouin zone “Fermi
arcs” , and high-energy “waterfall” anomalies as a consequence of matrix-element effects of disorder-localized
states in the charge-transfer gap of doped cuprates.
