Origin of the Large Entropy Change in the Molecular Caloric and Ferroelectric Ammonium Sulfate (Adv. Funct. Mater. 45/2022)
Source abstract
Abstract
Molecular Caloric In article number 2207717, Phillips and co-workers show that the large entropy change in the caloric material ammonium sulfate arises from librations of the ammonium ions in flat-bottomed, “bathtub-shaped” potential wells rather than an order-disorder phase transition. Engineering similar energy landscapes may be a promising route to designing new caloric molecular materials.
