PREPARATION OF YBA2CU3O7 SURFACES FOR PHOTOEMISSION-STUDIES BY INSITU OXYGEN ANNEALING
Clean surfaces of ceramic samples of the oxide superconductor YBa 2Cu3O7-x have been prepared in a UHV system by in situ annealing under pure oxygen at atmospheric pressure. Ultraviolet photoemission spectra from the oxygen-annealed surfaces are similar to those from cleaved single-crystal material....
