Abstract
Photoemission results show that water is physisorbed on a single-crystalline (001) face of the high-temperature superconductor Bi2Sr2CaCu2O8 at 90 K. A simple model of the electronic structure, in which Bi iii lone-pair electrons protrude from the surface, is suggested to account for the stability of this surface ultrahigh vacuum compared with other oxide superconductors. © 1990 The American Physical Society.
