Abstract

We compare the superlattice modulation, microstructure, and epitaxy of Tl₂Ba₂Ca₂Cu₃O₁ ₀ thin films grown on MgO [100] and SrTiO₃ [100] substrates by dc diode sputtering. Films grown on MgO were found to be quite clean with the c axis perpendicular to the substrate. However, no in-plane orientational relationship to the substrate was found. Films grown on SrTiO ₃, on the other hand, showed very good epitaxy to the substrate despite the presence of second phases. Films grown on MgO also exhibited a longer coherence length of the superlattice modulation than those grown on SrTiO₃ under identical conditions.
