Carrier Doping Effects on Copper 2p Core Level Photoemission in Cuprates

抄録

Carrier doping effects on the Cu 2p photoemission in low-dimensional cuprates are discussed on the basis of large-cluster model calculations. The result shows that the carrier doping causes a significant change in the line shape of the main structure in the Cu 2p spectrum. It is closely related to the change in the electronic structure near the Fermi energy of the system.
