Abstract

The dependences of the bulk photovoltaic effect on the composition fraction x, temperature, and on illumination wavelength have been investigated in the (1 minus x)PbTiO//3- xLa(Zn//2/////3Nb//1/////3)O//3 solid solution ceramics. The composition dependence of the photovoltaic current J//p//h shows a very similar tendency to that of the remanent polarization P//r, suggesting that J//p//h is directly related with P//r. On the contrary, the variation of the photocurrent with temperature measured in a sample with x equals 0. 105 reveals an anomalous peak just below the Curie temperature. These characteristics are discussed in comparison with the ceramic BaTiO//3 data by P. S. Brody.
