How space-charge behaviour at grain boundaries in electroceramic oxides is modified by two restricted equilibria
Adrian L. Usler, Fabian Ketter, Roger A. De Souza
Abstract
obtained from electrical and from imaging methods, differences that arise from the different measurement temperatures and that are aggravated by the restricted equilibria. We also show that grain-boundary widths determined from elemental acceptor-cation profiles will not, on principle, agree with the electrical width extracted from impedance spectroscopy data.
