dc.description.abstractObservations by X-ray photoelectron spectroscopy on LnBa2Cu3O7-x (Ln = Y and Ho) show that there are no significant surface electronic differences as a result of substitution of Y by Ho. The O 1s and Ba 3d envelopes exhibit fine structure which appears to be related to significant electronic and structural properties of the 1-2-3 compounds. Namely, the low-binding-energy component of the O 1s envelope is due to Ba-o bonding as well as being specific to the electronic linkage of the Cu layers in the orthorhombic structure. The anomalous low-binding-energy contribution to the Ba 3d envelope suggests that Ba may play an important electronic role as well as a structural role. There is further evidence that Sr and Ca play similar roles in the related Bi-Sr-Ca-Cu-O high-Tc compounds.
