Abstract : This work examines the thermal boundary resistance between high-Tc superconducting films and insulating substrates. In particular we compare c-axis and a-axis films and different oxygen stoichiometries. Comparison of c-axis films shows very little temperature dependence; a-axis films show strong temperature dependence from 100 K to room temperature. This temperature dependence disappears upon reducing the oxygen content of the films.
