Sn2P2S6films for memory devices with nondestructive readout

Abstract
The polarization switching processes of ferroelectric polycrystalline Sn2P2S6 films on Al substrates were studied. The effect of full reverse spontaneous switching after the influence of a repolarizing pulse on the prepoled sample was investigated. This opens the way for making the ferroelectric memory devices with rapid nondestructive readout.
