Abstract
Kinetic energy distributions of secondary ions emitted from Cs+-bombar ded oxygen annealed and argon annealed YBa2Cu3O7-delta (YBCO) samples and Ar+-bombarded Y2O3 have been measured. Surface binding energy of y ttrium (Y) and copper in the YBCO sample is found to be influenced by the structural changes and they are compared with that of Y in Y2O3. D ifference in the secondary ion emission from the two types of YBCO sam ples are explained in the light of their known structures.
