Abstract
This letter describes experiments using the scanning electron microscope in the electron beam induced current mode to image ferroelectric domains and grain boundaries in a positive temperature coefficient ceramic. The mechanism responsible for the observed contrast is discussed together with the relevance of the observations to a previously published hypothesis concerning the interaction between domains and grain boundary barriers.Keywords
