Abstract
It is shown that the short circuit photocurrent measured in BaTiO3:Fe and PLZT ceramics is proportional to the total polarization, i.e. spontaneous and field induced polarization. A possible explanation is found in the Franck Condon relaxation model, which shows that the effective field which drives the short circuit photocurrent is the field associated with the spontaneous polarization.Keywords
