METAL-TO-NON-METAL TRANSITIONS IN HIGH-TEMPERATURE OXIDE SUPERCONDUCTORS MONITORED BY PHOTOELECTRON-SPECTROSCOPY
Metal-to-non-metal transitions induced in Bi-Sr-Ca-Cu-O by cation substitution and in Y-Ba-Cu-O by oxygen deficiency are used to show that changes in the Cu 2p signature in X-ray photoemission may be correlated with the changes in the hole doping level on the Cu-O2 planes of these high-temperature s...
