Anomalous Refractive Index Modulation and Giant Birefringence in 2D Ferrielectric CuInP2S6

Advanced Optical Materials, Volume 13, Issue 35, December 12, 2025.
An unprecedented anomalous thickness‐dependent change in refractive index is reported in CuInP2S6 (δn$\delta{\rm n}$∼23.2%). Furthermore, CuInP2S6 also exhibits giant birefringence in the blue‐ultraviolet regime (|nOOP ‐ nIP|∼1.24), the largest of any known material within this wavelength regime.

Modeling of enhanced electrocaloric effect above the Curie temperature in relaxor ferroelectrics [PDF]

, 2011
The electrocaloric (EC) effect offers promise as a means to realize solid-state refrigeration, which requires EC materials possessing a pronounced pyroelectric effect over a broad temperature range.

LARGE ELECTROCALORIC EFFECT IN RELAXOR FERROELECTRICS

Journal of Advanced Dielectrics, 2012
Organic and inorganic relaxor ferroelectrics used for electrocaloric effect (ECE) applications are introduced. Relaxor ferroelectrics offer several advantages for ECE devices, e.g., infinite states without applying electric field, field-induced large polarization, no-hysteresis of heating and cooling, small-hysteresis polarization loss, room ...

Coexisting Phases in NaNbO3 Thin Films Influenced by Epitaxial Strain and Size Effects

Advanced Science, Volume 12, Issue 46, December 11, 2025.
Coherently strained NaNbO3 thin films are synthesized across a range of thicknesses, enabling the study of size effects under epitaxial strain in antiferroelectric thin films without relaxation. Competing antiferroelectric‐ferroelectric phases are observed, leading to the stabilization of phase coexistence, multistate switching with strong retention ...

Room temperature giant electrocaloric properties of relaxor ferroelectric 0.93PMN-0.07PT thin film

AIP Advances, 2013
In this paper, 0.93PMN-0.07PT thin film shows a giant electrocaloric effect at room temperature. At electric field shift of 723 kV/cm, the peak value of ΔS of 0.93PMN-0.07PT thin film is 13.05 J/K.kg. The largest change (12.24 °C in 15.18 V, i.e. 0.8 K/V)

Optical Control of the Thermal Conductivity in BaTiO3

Advanced Functional Materials, Volume 35, Issue 48, November 26, 2025.
Light‐driven manipulation of thermal conductivity in archetypal ferroelectric, BaTiO3, offers a novel and effective approach for the dynamical control of the heat flux, with potential applications in thermal management and phonon‐based logic. Abstract Achieving dynamic control over thermal conductivity remains a formidable challenge in condensed matter

Electrocaloric effect and freezing temperature in (Pb0.8Ba0.2)[(Zn1∕3Nb2∕3)0.7Ti0.3]O3 relaxor ferroelectric ceramic [PDF]

Journal of Advanced Dielectrics, 2016
The electrocaloric effect (ECE) is studied in (Pb0.8Ba0.2)[(Zn1∕3Nb2∕3)0.7Ti0.3]O3 relaxor ferroelectric ceramic by using an “indirect method”. The electric dependence for the polarization (hysteresis loops) has been obtained for several temperatures ...
