  • Title: Conduction at domain walls in insulating Pb(Zr0.2 Ti0.8)O3 thin films.
    Author: Guyonnet J, Gaponenko I, Gariglio S, Paruch P.
    Journal: Adv Mater; 2011 Dec 01; 23(45):5377-82. PubMed ID: 21956256.
    Abstract:
    Domain wall conduction in insulating Pb(Zr(0.2) Ti(0.8))O(3) thin films is demonstrated. The observed electrical conduction currents can be clearly differentiated from displacement currents associated with ferroelectric polarization switching. The domain wall conduction, nonlinear and highly asymmetric due to the specific local probe measurement geometry, shows thermal activation at high temperatures, and high stability over time.
