Photovoltaic and photoelectric response of Sn2P2S6 ferroelectric films

Abstract: In the present work, the comparative study of the electric response of Sn2P2S6 films to the visible light action was carried out without and under external electric field. The light flux modulated by a chopper induces the integral response comprising time-dependent photoelectric and photovoltaic components. It was shown that spontaneous polarization influences the electric response characteristics.
