Role of domain walls in the abnormal photovoltaic effect in BiFeO(3)

Recently, the anomalous photovoltaic (PV) effect in BiFeO(3) (BFO) thin films, which resulted in open circuit voltages (V(oc)) considerably larger than the band gap of the material, has generated a revival of the entire field of photoferroelectrics. Here, via temperature-dependent PV studies, we pro...
