Stress-Induced Phase Transitions in Nanoscale CuInPS
Anna N. Morozovska, Eugene A. Eliseev, Sergei V. Kalinin +2
Using Landau-Ginsburg-Devonshire approach and available experimental results we reconstruct the thermodynamic potential of the layered ferroelectric CuInPS (CIPS), which is…
Phenomenological description of bright domain walls in ferroelectric-antiferroelectric layered chalcogenides
Anna N. Morozovska, Eugene A. Eliseev, Kyle Kelley +3
Recently, a layered ferroelectric CuInP2Se6 was shown to exhibit domain walls with locally enhanced piezoresponse - a striking departure from the observations of nominally zero pie…
Room Temperature Electrocaloric Effect in Layered Ferroelectric CuInP2S6 for Solid State Refrigeration
Mengwei Si, Atanu K. Saha, Pai-Ying Liao +10
A material with reversible temperature change capability under an external electric field, known as the electrocaloric effect (ECE), has long been considered as a promising solid-s…
Analytical description of domain morphology and phase diagrams of ferroelectric nanoparticles
Anna N. Morozovska, Yevhen M. Fomichov, Petro Maksymovych +2
Analytical description of domain structure morphology and phase diagrams of ferroelectric nanoparticles is developed in the framework of Landau Ginzburg Devonshire approach. To mod…
Giant negative electrostriction and dielectric tunability in a van der Waals layered ferroelectric
Sabine M. Neumayer, Eugene A. Eliseev, Michael A. Susner +11
The interest in ferroelectric van der Waals crystals arises from the potential to realize ultrathin ferroic systems owing to the reduced surface energy of these materials and the l…
