Abstract

A comparative angle-resolved photoemission measurement has been performed on nonsuperconductive Bi₂Sr₂Ca_0.4Y_0.6Cu₂O₈ and superconductive Bi₂Sr₂CaCu₂O₈ to study the nature and origin of the electronic states near the Fermi level. It was found that hole-doping does not cause a rigid shift of the density of states relative to the Fermi level, but creates new electronic states in the vicinity of the Fermi level.
