摘要

oxide ceramics are dominated by the interaction of oxygen vacancies with extended defects. Here, oxygen vacancy segregation to grain boundaries in perovskite structured SrTiCb and fluorite structured Yttria stabilized Zirconia (YSZ) is analyzed by atomic resolution Scanning Transmission Electron Microscopy (STEM). For both types of structure, grain boundaries are found to contain an excess of oxygen vacancies compared to the bulk material.
