Abstract

Single crystal samples of BSCCO were cleaved in ultrahigh vacuum and studied using XPS with a monochromated Al Kα source. The resolution of the instrument is ~0.35 eV which is better than most previous XPS studies of BSCCO. We confirm that the shape of the Cu2pand O 1speaks imply multiple states. The samples were heatedin situto drive off O, to study how screening is affected by changes in stoichiometry. Auger parameters were used for this study. The Auger parameters of Bi, Ca, O, and Cu were estimated.
