CORE AND VALENCE LEVEL PHOTOEMISSION-STUDIES OF OXYGEN ANNEALED Y2BA4CU6+NO14+N (N=0,1,2) SURFACES
Atomically clean surfaces of the 123, 247 and 124 YBaCu oxide superconductors have been prepared for photemission studies by in situ oxygen annealing. They are characterised by simple lineshapes for the 01s core level in XPS and the absence of satellite structure at 9.5eV in valence level UPS. Atomi...

| description | Atomically clean surfaces of the 123, 247 and 124 YBaCu oxide superconductors have been prepared for photemission studies by in situ oxygen annealing. They are characterised by simple lineshapes for the 01s core level in XPS and the absence of satellite structure at 9.5eV in valence level UPS. Atomic ratios inferred from the intensities of XPS core lines demonstrate barium segregation at the surfaces of all three materials. © 1991. |
