Thermal, ferroelastic, and structural properties near phase transitions of organic–inorganic perovskite type [NH₃(CH₂)₃NH₃]CdBr₄ crystals

Abstract

We studied the thermal behavior and structural dynamics of [NH3(CH2)3NH3]CdBr4 near phase transition temperatures.

Synthesis and Characterization of a Displacement-Type Ferroelectric–Ferroelectric Phase Transition Compound [(NH3)(CH2)3(NH3)]2[InBr6]Br·H2O

“…At the same time, for organic–inorganic hybrid materials, many reports reveal that the phase transitions of some compounds are led by the displacements of anions or cations. − For example, Lim’s group synthesized a displacement-type phase transition material [(NH 3 )­(CH 2 ) 3 (NH 3 )]­CdCl 4 . The phase transition is mainly due to the displacement of [(NH 3 )­(CH 2 ) 3 (NH 3 )] 2+ cations . However, there are still few studies on displacement-type ferroelectric phase transition materials.…”

“…The phase transition is mainly due to the displacement of [(NH 3 )(CH 2 ) 3 (NH 3 )] 2+ cations. 32 However, there are still few studies on displacement-type ferroelectric phase transition materials. Therefore, it is very necessary to explore more organic−inorganic hybrid displacement-type ferroelectric phase transition materials.…”
