摘要：
Charge transport phenomena in porous ceramic PZT films are discussed. The leakage current has been found to be in PZT porous films is 1-1.5 orders higher than for the dense film throughout the whole bias voltage. In the low fields region (similar to 40-160 kV/cm) the main charge transport mechanism is the ohmic conductivity. Static (steady state) conductivity of porous PZT films is 1-2 orders higher than of dense film. The main possible charge transport mechanism in the high fields region (>= 160-180 kV/cm) is the space-charge-limited conduction.
