Unique Performance Considerations for Printable Organic Semiconductor and Perovskite Radiation Detectors: Toward Consensus on Best Practice Evaluation

Advanced Functional Materials, EarlyView.
A lack of standard approaches for testing and reporting the performance of metal halide perovskites and organic semiconductor radiation detectors has resulted in inconsistent interpretation of performance parameters, impeding progress in the field. This Perspective recommends key metrics and experimental details, which are suggested for reporting in ...

Exploring Electronic States and Ultrafast Electron Dynamics in AlInP Window Layers: The Role of Surface Reconstruction

Advanced Functional Materials, EarlyView.
This study examines the surface characteristics of AlInP (001), crucial for advanced solar cells and photoelectrochemical devices. Using theoretical modeling and experiments, it identifies how phosphorus‐rich and indium‐rich surfaces create mid‐gap states that pin the Fermi level and influence ultrafast electron dynamics.

Gate‐Tunable Hole Transport in In‐Plane Ge Nanowires by V‐Groove Confined Selective Epitaxy

Advanced Functional Materials, EarlyView.
Ge nanowires are promising for hole spin‐based quantum processors, requiring direct integration onto Si wafers. This work introduces V‐groove‐confined selective epitaxy for in‐plane nanowire growth on Si. Structural and low‐temperature transport measurements confirm their high crystalline quality, gate‐tunable hole densities, and mobility.

Ideal Molecular Sieving with a Dense MOF for Helium Upgrading with Highly Diffusion Selective Mixed Matrix Membranes

Advanced Functional Materials, EarlyView.
The separation of Helium gas from natural gas is challenging but highly important. MIL‐116(Ga), a “non‐porous” metal–organic framework is used as a molecular sieve to separate He from CH4. Druse‐like MIL‐116(Ga) particles are integrated into polysulfone mixed matrix membranes.

Carbon Nanotube 3D Integrated Circuits: From Design to Applications

Advanced Functional Materials, EarlyView.
As Moore's law approaches its physical limits, carbon nanotube (CNT) 3D integrated circuits (ICs) emerge as a promising alternative due to the miniaturization, high mobility, and low power consumption. CNT 3D ICs in optoelectronics, memory, and monolithic ICs are reviewed while addressing challenges in fabrication, design, and integration.

Hydrophobic Deep Eutectic Solvent (DES) Design Enables Optimally Hydrated DES‐in‐Water Electrolytes for High‐Performance Bromine Redox‐Enhanced Energy Storage Systems

Advanced Functional Materials, EarlyView.
Faradaic charging with bromine redox chemistry shows promise for energy storage, yet its efficient use in aqueous electrolytes is hindered by water decomposition and polybromides' cross‐diffusion, leading to suboptimal cell performance. This study introduces a tetrabutylammonium bromide‐based hydrated deep eutectic electrolyte with optimized water ...

Highly Efficient 3D‐Printed PVDF‐Based Triboelectric Nanogenerators Featuring Polymorphic Perovskite Nanofillers

Advanced Functional Materials, EarlyView.
This study demonstrates the use of a low‐cost 3D printing technique to prepare a large‐area PVDF‐FAPbI3 composite dielectric film for flexible TENG application. The δ→α phase transformation of the FAPbI3 nanofillers has significantly improved the β‐phase content, morphology, and dielectric properties of the PVDF film.
