P. Srivastava et al., CORE-LEVEL PHOTOEMISSION-STUDY ON A BI-2212 SINGLE-CRYSTAL, Materials science & engineering. B, Solid-state materials for advanced technology, 22(2-3), 1994, pp. 217-221
A high quality Bi-2212 single crystal has been studied using core-leve
l photoemission. The presence of high binding components in Bi (4f) an
d Cu (2p) spectra have been correlated with the different components o
bserved in the O (1s) spectra and the effect of extra oxygen in the Bi
-O planes. The results of Sr (3d), Ca (2p), Cu (2p) and Bi (4f) core-l
evel spectra are discussed in detail.
