- Abstract:
-
A simple chemical thinning process has been developed which allows high-quality TEM specimens to be prepared from bulk Y1Ba2Cu3O7-x (YBCO) material. This enabled the microchemistry of a statistically significant number of grain boundaries, with a wide range of misorientations, to be studied using TEM, STEM and EDX techniques. In YBCO samples where the overall stoichiometry is exactly 1:2:3 no unreacted CuO, BaCO3 or Y2O3 are present as grain boundary phases. Significant traces of segregated i...
