Correlation between the in situ growth conditions of YBCO thin films and the thermodynamic stability criteria

Abstract Data from the literature on the successful in situ growth of YBCO thin films in terms of the growth temperature and the oxygen pressure are compared with the thermodynamic stability as determined by an electrochemical method. The correlation over a wide range of growth temperatures and oxygen pressures, and for most methods of deposition, suggests that proximity to the equilibrium decomposition line may be favorable for in situ growth.
