“…It is known that some ferroelectric films exhibit a photovoltaic response to modulated light radiation . In many cases, the observed photovoltaic and photoelectric responses are due to interface effects as well as to optical exchanging the charge of local levels (traps).…”

In this paper, comprehensive investigation of the pyroelectric properties and local piezoelectric response in ferroelectric film heterostructures is presented. The pyroelectric effect is determined by the dynamic method and the pyroelectric response is recorded for further analysis. It is shown that such studies are effective to analyze the self-polarization phenomena, the stability of the polarized state, the determination of the ferroelectric phase fraction in the film structures, the characterization of grains with inplane and out-of-plane polarization and others. For example, thin film samples of ferroelectric LiNbO 3 deposited by magnetron sputtering on silicon substrates are considered. The measurement results show that a part of the crystal grains (about 30%) in these films possessed the out-ofplane polarization directed from the free surface to the substrate and determined the peculiarities of the pyroelectric response and the vertical component of the local piezoelectric response.

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.

“…However, further progress in crystal elaboration requires a better understanding of its parameters. The physical and chemical properties of the SPS single crystal have been experimentally 2,[6][7][8]11,[17][18][19][20][21][22][23][24] as well as theoretically 11,[25][26][27][28] studied. The energy band structures of both the FE and PE phases were investigated via the rst principle calculations using the DFT methodology.…”
