WebMar 22, 2016 · These results highlight the potential of the OMHP architecture for designing new functional photoferroelectrics and photopiezoelectrics. Piezoelectrics play a critical role in various applications. The permanent dipole associated with the molecular cations in organometal halide perovskites (OMHPs) may lead to spontaneous polarization and thus ... WebThus, we shall use the term photoferroelectrics to refer to crystals which change their ferroelectric properties (or properties connected with the spontaneous polarization in one way or another) when optically excitated in the intrinsic or extrinsic region of the spectrum.

WebFeb 7, 2011 · Abstract. A substantial increase in photoferroelectric image storage sensitivity has been achieved in ferroelectric-phase PLZT ceramics by implanting protons (H + ions) into the image storage surfaces. The 10- to 100-fold increase in sensitivity is attributed to increased densities of carrier photoexcitation and trapping centers and to an increase in …
