Negative thermal expansion (NTE) is fascinating as it involves a material's volume contraction rather than expansion upon heating. Although NTE ...

The Team from Huazhong University of Science and Technology Reveals the Electro-Optic Effect Mechanism and Future Applications of Ferroelectric ...

Abstract: Perovskite ferroelectrics (PFs) have been the dominant piezoelectric materials for various electromechanical applications, such as ultrasonic transducers, sensors, and actuators, to name a ...

Their paper, published in Physical Review Letters, theoretically demonstrates that some ferroelectric perovskites could exhibit giant photocaloric (PC) effects, which persist across a far wider ...

DJ-type perovskites have a layered octahedral structure, which makes the layers asymmetrical, giving them ferroelectric properties. The ferroelectric properties are caused by the shifting of ...

A key innovation in this work is the use of a photoferroelectric perovskite. Ferroelectric materials possess a spontaneous electric polarization that can be reversed by an applied electric field. In ...

A team of material scientists led by Bingcheng Luo from the Department of Applied Physics at China Agricultural University recently outlined the state of perovskite-based ferroelectric ceramics for ...

Barium titanate belongs to the perovskite group of materials, where a titanium ion resides within an oxygen octahedral cage. The material exhibits displacive-type ferroelectric behavior ...

CAS Key Laboratory of Nanosystem and Hierachical Fabrication CAS Center for Excellence in Nanoscience, National Center for Nanoscience and Technology, Beijing 100190, People’s Republic of China State ...

Episode 57 of the Factor This! podcast features Joseph Berry, a perovskite researcher at the National Renewable Energy Laboratory, and Paul Warley, the CEO of Ascent, a company working to ...
