The Anomalous Photovoltaic Effect in Ferroelectrics

Part of the Springer Series in Solid-State Sciences book series (SSSOL, volume 9)


It is well known that the photovoltage in semiconductors, whatever its nature, cannot exceed the energy gap, which is several volts. For instance, in a homogeneous semiconductor the Dember (diffusion) photovoltage does not exceed the following value [3.6] for an infinitely large intensity of the exciting light:
$$ V = \frac{{kT}}{q}\ell n\frac{{{n_1}}}{{{n_0}}} < < \frac{{kT}}{q}\ell n\frac{{{N_c}}}{{{n_0}}} = {E_g}.$$
