P. Rajasekar et al., X-RAY PHOTOELECTRON-SPECTROSCOPY (XPS) STUDIES OF O1S CORE-LEVEL IN Y-DOPED BI-2212 SUPERCONDUCTOR, Journal of the Korean Physical Society, 32(3), 1998, pp. 365-367
X-ray Photoelectron Spectroscopy (XPS) studies on Ols core levels of Y
-doped Bi2Sr2CaCu2O8+delta (Bi-2212) have been carried out and are com
pared with XPS studies on Ols core levels of the undoped Bi-2212. The
results are discussed in terms of hole concentrations of the metal-oxy
gen layers.
