Abstract

An analysis of diffusion mechanism of cation-exchange process for fabrication of HgBa₂CaCu₂O_6+δ superconducting films was discussed. A systematic study on conversion of Tl₂Ba₂CaCu₂o₈ precursor films to HgBa₂Cacu₂O₆ films was done. Results suggest that the pathway of Hg cations in thin films is to channel through defects across the thickness of films and then diffusion into grains takes place.
