Notes:
The conversion of semiconductive SrCuO2 "infinite layer'' epitaxial films into a metallic and superconducting (Tc(approximately-equal-to)30 K) oxycarbonate phase related to Sr2CuO2(CO3) has been induced by thermal processing in oxidizing ambient containing a small amount of CO2. Ion beam analysis using the resonant 12C(p,p)12C elastic backscattering cross section for protons incident at 1.73 MeV confirms the presence of substitutional C in the converted perovskite lattice. Comparison of the threshold CO2 partial pressure with thermodynamic stability data for SrCO3 suggests that the conversion is initiated by the high affinity of Sr(O) for CO2. © 1995 American Institute of Physics.
