Abstract

Static simulation techniques have been used to examine the defect chemistry in heteroepitaxial ceramic interfaces. Reduced ion density at the interface is seen to enhance the interfacial stability. The energetics of defect formation are shown to be substantially modified at the interface. In particular, we find that the energy of oxygen vacancy formation is lower at the interface between CeO2 thin films on α-Al2O3 compared with its value on the pure CeO2 surface. This effect of the interface may influence the catalytic activity of several systems. © 1994 The American Physical Society.
