Structure and Properties Impacting Ferroelectricity in Sn<sub>2</sub>P<sub>2</sub>S<sub>6</sub>
ORAL
Abstract
Sn2P2S6 samples prepare under various conditions including chemical vapor transport and the Bridgman method exhibit marked variations in optical and dielectric properties. To understand the origin of these changes, detailed measurements of the thermal properties by specific heat methods are combined with structural measurements on multiple length scales. We link critical temperature-dependent structural changes with enhanced electronic properties.
