Is There A Pure Electronic Ferroelectric?

open access: yesAdvanced Electronic Materials, Volume 12, Issue 3, 4 February 2026.
The search for faster, more reliable ferroelectric materials has shifted from traditional lattice‐driven ferroelectrics, which rely on slow ionic displacements, to electronic ferroelectrics, where polarization is governed by electronic ordering. This shift enables ultrafast switching, low‐field operation, and resistance to fatigue.

Possible Peierls Distortion Through Re2 Dimer Formation in the LaNiO2‐Type Nitrides LnReN2 (Ln = Pr, Nd)

open access: yesAngewandte Chemie International Edition, Volume 65, Issue 5, 28 January 2026.
This study presents the high‐pressure synthesis of two new anion‐vacancy‐ordered perovskite‐related nitrides, PrReN2 and NdReN2, featuring distorted LaNiO2‐type structures. X‐ray and neutron diffraction reveal a structural distortion driven by dimerization of Re‐chains, while electronic structure calculations reveal the simultaneous presence of ...
