Liquid-matter relaxor ferroelectrics by design [PDF]

Nature Communications
Knowing that traditional relaxor ferroelectrics stem from crystalline materials, one may ask whether they stabilize the liquid-matter analogy. The perspective is challenging and may enable a generic design of fluidic and flexible relaxor ferroelectrics ...

Deciphering the atomic-scale structural origin for large dynamic electromechanical response in lead-free Bi0.5Na0.5TiO3-based relaxor ferroelectrics [PDF]

Nature Communications, 2022
For relaxor ferroelectrics, correlating their properties and local structures is challenging. Here, the authors correlate the atomic-scale structure and the large dynamic electromechanical property in Bi0.5Na0.5TiO3-based relaxor ferroelectrics.

High Entropy Oxide Relaxor Ferroelectrics [PDF]

ACS Applied Materials & Interfaces, 2022
Relaxor ferrolectrics are important in technological applications due to a strong electromechanical response, energy storage capacity, electrocaloric effect, and pyroelectric energy conversion properties. Current efforts to discover and design new materials in this class generally rely on substitutional doping of known ferroelectrics, as slight changes

Optical Properties and Model of Relaxor Ferroelectrics [PDF]

Ferroelectrics, 2003
Phenomenological approach to a relaxor theory is developed and some experi-mental results in the support of this theory are received. The optical absorption spectrum, luminescent emission and photoconductivity are investigated in the wide temperature region in PbMg 1/3 Nb 2/3 O 3 .

Non-steady-state optothermal electromotive force in relaxor ferroelectrics [PDF]

Scientific Reports
We predict a new non-steady-state optothermal electromotive force effect in relaxor ferroelectrics. The effect is observed and studied in a PbNi $$_{1/3}$$ Ta $$_{2/3}$$ O $$_3$$ crystal at light wavelength $$\lambda =532$$ nm and room temperature, which

Charge Localization in the Model of Relaxor Ferroelectrics [PDF]

Ferroelectrics, 2003
Phenomenological approach to a relaxor theory is developed and some experimental results in the support of this theory are received. The optical absorption spectrum, luminescent emission and photoconductivity are investigated in the wide temperature region in PbMg 1/3 Nb 2/3 O 3 . On the basis of this data the density of states on the impurity band and
