Abstract
High quality single crystals of Bi-2212, Tl-2212 and Tl-2223 were stud ied using X-ray photoelectron spectroscopy. From a deconvolution of th e Cu2p(3/2) main line, we have shown that the density of O 2p holes in the Cu-O planes are qualitatively similar in case of the Bi and Tl-22 12 systems even though they have shown many other differences in their electronic structure properties. Also the results show a dependence o f the density of holes on the number of Cu-O planes as we go from Tl-2 212 to Tl-2223.
