Theoretical investigation of possible low-lying electronic excitations in YBa2Cu3O7−x

  • L. A. Curtiss (a1) and S. W. Tam (a1)

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.

18The Jahn-Teller distortion in La2–x Bax CuO4 (CuOax = 2.42 Å; CuOeq = 1.89 Å) is very similar to the Jahn-Teller distortion (Ref. 19) forCu2+ in water (four H2O molecules at 1.94 Å and two at 2.43 Å). Ab initio calculations that we have carried out on [Cu(OH2)6]2+ using a minimal basis set gives a CuOax distance of 2.20 Å and a CuOeq distance of 1.98 Å. Although the CuOax distortion is not nearly as large, the potential energy surface for stretching this bond is very shallow.
