Current-voltage characteristics for lead zirconate titanate bulk ceramics.

Abstract
Current-voltage characteristics have been obtained on lead zirconate titanate bulk ceramics using robust measurement techniques separating polarization effects from actual charge transport. Measurement of the electrical conduction upon both increase and decrease in the electric field shows that long settling times are required to suppress polarization currents and obtain reliable data. The influence of additional field cycles and different electrode materials is also studied. The analysis reveals that an Ohmic conduction is dominant at low fields, while at high fields charge transport is most likely governed by space charge limited currents.
