Electrical properties of the lead lanthanum zirconate titanate

Abstract This paper reports electrical properties of the lead zirconate titanate system including lead lanthanum zirconate titanate. Some compositions of the lead zirconate titanate system materials have photovoltaic effect, which is applicable to the micro electro-mechanical systems. Sample preparation was carried out in use of the conventional solid state reaction method. Density and dielectric constant were obtained as a suitable value. These samples have the perovskite structure that is confirmed by X-ray diffraction method. The dark conductivity and also photoconductivity are estimated in use of the high-resistance electrometer. Some proposal was shown for the development on the photovoltaic effect from the material view of points.
