Large low-field-driven electrocaloric effect in organic-inorganic hybrid TMCM-CdCl₃.

ABSTRACT: Due to environmental-friendliness and high-efficiency, electrocaloric effect (ECE) is widely regarded as a refrigeration technology for tomorrow. Herein, utilizing organic-inorganic hybridization strategy, we achieve the largest low-field-driven ECE and highest directly-measured electrocaloric strength (ECS) via packing sphere-like organic cation (CH₃)₃NCH₂Cl⁺ (TMCM⁺) into inorganic one-dimension (1-D) CdCl₃ chain framework. Single-crystal X-ray (SC-XRD) diffraction combined with Raman Spectra reveals that the simultaneous order-disorder transition of organic cations and dramatic structure change of inorganic framework are responsible for the large ECE. Moreover, the measured P-E loops and density function theory (DFT) calcu
