Pairing Non‐Fullerene Acceptors With the Right Polymer: Impact of Phase Morphology and Short‐Range Transport on Charge Generation

Advanced Electronic Materials, EarlyView.
This study investigates polymer requirements for pairing with high‐efficiency non‐fullerene acceptors (NFA) in organic photovoltaics by comparing three polymer blends across varied phase morphologies. The generation of free charges is driven by fast transport‐assisted charge separation combined with slow intrinsic recombination.

Dual‐Defect‐Engineered Zinc Oxynitride Thin‐Film Transistors Enabling Electrostatic Current Balancing in Geometrically Symmetric Oxide Logic

Advanced Electronic Materials, EarlyView.
Dual‐defect engineering controls subgap states in zinc oxynitride (ZnON) thin‐film transistors, yielding a field‐effect mobility of 26.58 cm2 V−1 s−1. A process‐associated threshold‐voltage shift is repurposed within a dual‐gate depletion‐mode load to electrostatically balance current in a geometrically symmetric NMOS inverter.

Simultaneous Electronic and Crystallographic Modulation of Cs3Bi2Br9 by Single‐Element Sn Substitution for Enhanced CO2 Photoreduction

Advanced Energy Materials, EarlyView.
Aliovalent B‐site substitution with Sn2+ in lead‐free perovskite, Cs3Bi2Br9, is employed to simultaneously induce lattice contraction and bromine vacancy through charge imbalance and ionic radius mismatch. The resulting structural distortion modulates the electronic structure and improves charge separation, leading to enhanced visible‐light‐driven CO2 ...

MXene‐Derived Highly Oriented TiN Enables Ta3N5 Photoanodes for Transmission‐Mode Bias‐Free Solar Water Splitting

Advanced Energy Materials, EarlyView.
This work reports 2D MXene‐derived TiN thin films with (111)‐preferred orientation for transparent Ta3N5 photoanodes, demonstrating effective electron transfer behavior. All‐nitride electron‐collection architecture based on MXene‐derived TiN and n‐GaN resolves a long‐standing materials bottleneck between photocarrier transport and light transmission in

Dimensional Reduction of Transition Metal Dichalcogenides by Oxide Insertion: Quasi‐1D Oxychalcogenide Semiconductors

Angewandte Chemie, EarlyView.
Molecular Scissors: Oxide insertion slices the layers of MQ2 transition metal dichalcogenides (TMDs) into one‐dimensional [M3Q6] nanoribbons, giving a new family of A2Hf3Q6O (A = K, Rb, Cs; Q = S, Se) oxychalcogenides. The heteroanion‐driven dimensional reduction yields direct‐gap semiconductors with optical absorption that is tunable across the ...
