Ferroelectricity in bis(ethylammonium) pentachlorobismuthate(III): Synthesis, structure, polar and spectroscopic properties

Abstract

A brief description of the thermal, structural and dielectric properties of bis(ethylammonium) pentachlorobismuthate(iii) ferroelectric with Ps that equals to 1.4 μC cm-2 at 180 K is presented. This paper focuses in particular on the molecular mechanism of a phase transition that is related mainly to the deformation of the anionic sublattice confirmed by temperature-variable powdered UV-Vis spectroscopy.
