Theoretical investigation of possible low-lying electronic excitations in YBa2Cu3O7−x
Published online by Cambridge University Press: 31 January 2011
Abstract
Ab initio molecular orbital calculations of oxygen 2p hole states of small CuO clusters representing the chains and planes in YBa2Cu3O7−x are reported. The results suggest that the absorption observed at 0.37 eV in reflectivity studies of YBa2Cu3O7−x may be due to excitation of these holes between inequivalent oxygen sites.
