THE CHARGE MECHANISM IN FERROELECTRICS.

Abstract

The charge transport mechanisms in lead zirconate titanate (Pb(ZrxTi1-x)O3) have been investigated over the range of temperatures from 650 degrees K to 1000 degrees K, by means of an electrochemical concentration cell. Very interesting results have been obtained at the higher temperatures, above 800 degrees K. These data suggest that the electrical conductivity, which is primarily ionic at these temperatures, exhibits an isolated peak in electronic conductivity at a temperature which increases with titanium concentration. Existing electrical shielding problems will soon be solved so that the measurements can be extended to lower temperatures, which will include the ferroelectric phase. (Author)
