Abstract
Chemical diffusion of oxygen in a 300nm thick c-axis-oriented YBa2Cu3O 7-delta film, deposited on (100) SrTiO3 by laser ablation, has been st udied by tracer O-18 and secondary ion mass spectroscopy (SIMS). Based on the case of semi-infinite diffusion with boundary condition of pre served surface concentration, D(appa.=)1.02x10(-14) cm(2)/s, the appar ent chemical diffusion coefficient along the normal to the film surfac e, was obtained.
