Nonstoichiometry in SrTiO3
Source abstract
Abstract
The defect chemistry of polycrystalline has been studied by means of the equilibrium electrical conductivity as a function of temperature, oxygen activity, Sr/Ti ratio, and impurity additions. Reduction, excess , and acceptor impurities all contribute to the oxygen vacancy content and their effects are therefore highly interdependent. The effect of added donor‐impurities, e.g. , 500 ppm Nb, is highly dependent on the presence and amount of excess .
