Directing Near‐Perfect (001) Orientation in Wafer‐Scale BiOI Thin Films via Halide‐Mediated van der Waals Stacking

open access: yesAdvanced Materials, EarlyView.
Our work introduces a new framework that fundamentally changes how orientation in bismuth oxyhalide systems is approached. Comprehensive experiments, backed by theoretical models, reveal the pivotal role of halide anions to modify the van der Waals stacking energies required to direct orientation. Our method enables the fabrication of near perfect (001)

Decoding Synergistic Pathways in Bimetallic MOFs for Advanced Oxidation Processes

open access: yesAdvanced Materials, EarlyView.
This review presents a unified framework linking metal pairing and framework design with electronic structure, redox cycling, oxidant activation, reactive‐species generation, and catalytic performance across photocatalytic and oxidant‐based BMOF‐AOPs. The resulting design principles guide the development of hydrolytically stable and efficient BMOFs for

Cooperative Goniopolar and Anomalous Nernst Transverse Thermoelectricity in Kagome Magnets

open access: yesAdvanced Materials, EarlyView.
A cooperative transverse thermoelectric mechanism is realized in kagome magnets, where axis‐dependent goniopolar effects and Berry curvature‐driven anomalous Nernst coexist within the same energy window. In MgMn6Sn6, this intrinsic synergy yields a record room‐temperature transverse thermopower of 15.6 µV K−1, establishing a general strategy for high ...

Spectrally Programmable Spin‐Polarized Photocurrents in WSe2–NiPS3 Magnetic van der Waals Heterostructures

open access: yesAdvanced Materials, EarlyView.
Heterostructure photodiode devices of p‐type WSe2 with n‐type NiPS3 constructs spectrally protected spin‐polarized photocurrents. The energy of the excitation photon serves as an independent control parameter for spin‐selective photocurrent generation. ABSTRACT Efficient generation and control of spin‐polarized currents in semiconductors remain central

Poly(Alkoxythiophene) Rod‐Coil Block Copolymers for Organic Electrochemical Transistors

open access: yesAdvanced Materials, EarlyView.
We present the first synthesis of poly(3‐alkoxythiophene) rod‐coil block copolymers as a new architecture for OMIECs. Incorporating PEG and PLLA coils can enhance device performance beyond the homopolymer. The figure‐of‐merit depends uniquely on coil length.

Spectral Selective and Low‐Noise Thin‐Film Organic Photodetectors Enabled by Electric‐Field Engineering

open access: yesAdvanced Materials, EarlyView.
Molecular doping redistributes the internal electric field in organic photodetectors, providing a new degree of freedom to spatially control carrier transport and collection. Simulations and experiments reveal distinct transport pathways for injected and photogenerated carriers, enabling low dark current under reverse bias and wavelength‐selective ...

Strong Coupling in Bulk Nanoplasmonic Nanoplatelet Perovskite Scintillators

open access: yesAdvanced Materials, EarlyView.
A bulk scintillating nanocomposite is engineered from CsPbBr3 nanoplatelets and Ag nanocubes to support exciton–plasmon strong coupling under X‐ray excitation. The resulting hybrid polaritonic states appear directly in radioluminescence, opening a route toward polariton‐enabled scintillator design beyond conventional Purcell enhancement.
