Advanced Materials, Volume 38, Issue 1, 2 January 2026.Van der Waals heterostructures offer exciting possibilities for artificial materials with unique optical, electronic, and spintronic properties. However, their use in the terahertz (THz) range is limited due to material constraints. This study demonstrates scalable, large‐area, crystalline 2D heterostructures, combining topological insulators ...

Efficient Broadband Terahertz Generation by Above‐Band‐Gap Excitation of the Pyroelectric ZnSnN2
Advanced Optical Materials, Volume 14, Issue 1, 9 January 2026.Photo‐induced THz emission from the pyroelectric semiconductor ZnSnN2 is studied. For above‐band‐gap excitation, an ultrabroadband THz pulse is generated covering the range from 1 to 30 THz without any spectral gaps. The THz‐generation efficiency is about three orders of magnitude higher than that from a standard THz source like ZnTe with a similar ...

Flexoelectric Polarization Enhancement in Paraelectric BaHfO3 via Strain Gradient Engineering
Small, Volume 22, Issue 4, 16 January 2026.A strain gradient exceeding ≈105 m−1 in coherently grown BaHfO3 thin films induces a 29‐fold enhancement in field‐induced polarization. These results demonstrate flexoelectric coupling in a centrosymmetric paraelectric oxide thin film, offering a route to polarization control without relying on ferroic phase transitions.

Magnetic and ferroelectric orderings in multiferroic alpha-NaFeO2
, 2016 The triangular based antiferromagnet α-NaFeO2 has been studied by magnetization, dielectric, and neutron diffraction measurements as a function of temperature and magnetic field. The appropriate (HâT) phase diagram was constructed revealing a complex behavior due to a competition between several magnetic phases.

A New Platform for Twistronics: Perovskite Moiré Superlattices Beyond van der Waals
Small Structures, Volume 7, Issue 1, January 2026.This Perspective highlights perovskite moiré superlattices as a non–van der Waals platform for twistronics. Owing to ionic–covalent bonding and soft octahedral lattices, perovskites support deep moiré potentials and room‐temperature excitons. Recent progress in two‐dimensional Ruddlesden–Popper perovskites and three‐dimensional perovskite lamellae is ...
