THz‐Driven Coherent Phonon Fingerprints of Hidden Symmetry Breaking in 2D Layered Hybrid Perovskites

open access: yesAdvanced Materials, Volume 38, Issue 4, 16 January 2026.
Intense THz pulses are employed to drive coherent phonons in 2D Ruddlesden‐Popper hybrid metal‐halide perovskites (HOIPs) from the (PEA)2(MA)n‐1PbnI3n+1 family, revealing mode‐selective spectroscopic signatures of inversion symmetry breaking in those nominally centrosymmetric materials. These findings provide a handle to decode nonlinear phonon driving

Dynamically Tunable Coherent Perfect Absorption Based on Bound States in the Continuum in Borophene Metamaterials

open access: yesAdvanced Photonics Research, Volume 7, Issue 1, January 2026.
This article proposes a symmetry‐protected bound states in the continuum mechanism based on borophene metamaterials, achieving dual‐band broadband coherent perfect absorption (CPA) in the near‐infrared spectrum. By dynamically modulating carrier concentration, the operational bandwidth of CPA can be significantly expanded, effectively overcoming the ...

Reducing Coercive Field and Improving Endurance in Ferroelectric Epitaxial Hf0.5Zr0.5O2 Thin Films via Novel Interface Layer Approach

open access: yesAdvanced Science, Volume 13, Issue 5, 27 January 2026.
An ultrathin samarium doped hafnium zirconium oxide (Sm:HZO) underlayer reduces coercive field by ∼25% and enhances endurance tenfold in epitaxial ferroelectric HZO overlayer. The Sm:HZO interface allows redox mitigated oxygen exchange and lowers switching barriers, achieving stable polarization with enhanced endurance performance.
