Photovoltages in Ferroelectric Films,
Abstract
Polarization-dependent steady photovoltaic currents were found in thin lead zirconate-titanate films on silicon substrate. In addition to a polarization-dependent current, there was a steady non-polarization-dependent background current. There were also transient photo-voltaic currents that appeared once, in an initial response to illumination, after the remanent polarization is switched. For mercury arc illumination and a 0.25-gm-thick, sol gel process, 53/47 Zr/Ti ratio film, the polarization -dependent current was equal to 2.7 A/C per W/cm2.
