Electric‐Field Control of Terahertz Response via Spin‐Corner‐Layer Coupling in Altermagnetic Bilayers

Advanced Science, EarlyView.
A spin‐corner‐layer coupling mechanism is proposed in 2D altermagnetic bilayers. Exemplified by NiZrI6, the spin, layer, and topological corner states are simultaneously controlled by an ultralow electric field, enabling active modulation of terahertz absorption, emission, and polarization.

Chemical Doping Engineering of Polarization and Topological Textures in van der Waals Ferroelectric CuInP2S6

Advanced Science, EarlyView.
Our work reports that Li⁺ doping in CuInP2S₆ induces coexistence of high‐ and low‐polarization states, which fosters a rich spectrum of topological polar textures, such as bubbles and labyrinth domains. An unconventional flexoelectric effect is also discovered, where strain gradients can mechanically manipulate these polarization states and their ...

Synergistic Spin‐Polarization and Single‐Atom Engineering in Magnetic Heterojunctions for Efficient Solar Water Splitting

Advanced Science, EarlyView.
High‐throughput screening led to the identification of 67 Z‐scheme heterojunctions (comprising 2D magnetic transition metal halides and non‐magnetic transition metal chalcogenides). For CrI3/MoTe2 and CrI3/WTe2, electronic structure analysis demonstrated that synergistic crystallographic point group and built‐in electric field effects generate a ...

Emergent Spin Fluctuation and Structural Metastability in Self‐Intercalated Cr1+xTe2${\rm Cr}_{1+x}{\rm Te}_2$ Compounds

Advanced Electronic Materials, EarlyView.
Metastable superstructure and emergent spin fluctuation in self‐intercalated Cr1+xTe2${\rm Cr}_{1+x}{\rm Te}_2$ ABSTRACT Intercalated van der Waals (vdW) magnetic materials host unique magnetic properties due to the interplay of competing interlayer and intralayer exchange couplings, which depend on the intercalant concentration within the van der ...

Singlet Fission in Push–Pull Para‐Azaquinodimethane Films under the Gaze of Time Resolved Optical and Magnetic Spectroscopy

Angewandte Chemie, EarlyView.
New push–pull para‐azaquinodimethane derivatives were synthetized through a sustainable protocol. Transient absorption results showed ultrafast intermolecular singlet fission (SF) in film and demonstrated for AsOMe higher triplet energy than for literature SF materials, with intriguing perspectives for photovoltaics toward silicon matched SF.
