An anisotropic photoconductivity has been discovered in the ferroelectric Pb5Ge3On. In a field Ε = 1.5 kV/cm, an electric-field-induced transverse photocurrent is comparable in magnitude to the photovoltaic current in the absence of a field. The mechanism for transverse photoconductivity under the experimental conditions is analyzed.
