Low temperature phase transitions in ferroelectric tris-sarcosine calcium chloride (TSCC)

Abstract: Small-molecule based ferroelectrics offer several advantages over the currently used materials based on heavy metal oxides (i.e. cost, environmental-friendliness). There are relatively few well-characterised examples of molecular ferroelectrics, in part since the relevant crystallographic studies have relied on X-ray diffraction. Neutron diffraction is the key technique in understanding the behaviour of H-atoms in molecular crystals. Here, we propose to study a well-known but still poorly understood 'model' molecular ferroelectric, TSCC, based on an amino-acid-salt complex. TSCC is proposed to have four phases as a function of temperature, with transitions at 130, 64 and 42 K. The two highest T phases have been characterised structurally, but only by XRD. Information on the behaviour of H-atoms is essential. The lower two phases have not yet been studied at all, crystallographically.
