CONTRIBUTION OF FERROELECTRIC AND NON-FERROELECTRIC FACTORS TO P–E HYSTERESIS LOOPS OF CuInP2S6-TYPE SINGLE CRYSTALS

Abstract

A defining property of ferroelectricity is the switching between different states by the application of an electric field. Hysteresis loops serve like a fingerprint of ferroelectric materials giving some useful informa-tion. Sometimes the interpretation of information extracted from hysteresis measurements can be chal-lenging due to the non-ferroelectric factors such as electrical conductivity, defect dipole presence and/or dielectric properties. In this paper, the ferroelectric and non-ferroelectric factors on P–E hysteresis loops were investigated in a CuInP2 S6-type single crystal. The analysis of data obtained for this single crystal al-lowed extracting the reliable values in the materials with a low polarization and a high conductivity.
