Abstract

The electronic structure of TlCa2Ba2Cu3O9 (Tl1223) and its change by oxygen reduction or anion substitution is investigated by using the scalar-relativistic full-potential linearized augmented-plane-wave method. Electronic structure of Tl1223 is almost similar to the homologous system, Tl1212. However, reduction of oxygen, or substitution of flourine by oxygen induce a great change for Tl6s band, and this band crosses the Fermi level and additional carriers are introduced onto this new band. This behavior is confirmed by the X-ray photoemission spectroscopy. (C) 2001 Elsevier Science B.V. Allrights reserved.
