Abstract:

The increase and relaxation of the conduction current caused by formation of intergrown charged domain walls (CDW) during polarization reversal have been studied in stoichiometric lithium niobate. The 10(3)-10(4) times increase of the conduction current was revealed in the temperature range 100-200 degrees C. The current, measured during polarization reversal, consists of the conventional switching current and the conduction current along CDW dominating for T>200 degrees C. The model based on the complex conductivity pathway along CDW was proposed. The current data were analyzed in terms of the Kolmogorov-Avrami model taking into account the input of the CDW conductivity.
