Balancing Injection and Short‐Channel Effects in Organic Permeable Base Transistors via Thickness Scaling

open access: yesAdvanced Electronic Materials, EarlyView.
Organic permeable base transistors are shown to benefit from balanced control of the semiconductor layers above and below the permeable base. Simulations and experiments indicate that the top semiconductor layer affects charge injection and lateral transfer length, while the bottom layer modulates the collector‐induced short‐channel effects.

Ultrahigh Detectivity Colloidal Quantum dot Avalanche Photodetectors Driven by Electron Mobility of the n‐Type Layer

open access: yesAdvanced Electronic Materials, EarlyView.
Herein, electron mobility of the n‐type layer is demonstrated to be a key parameter governing detection performance in CQD‐APDs through a comparative study of ZnO nanoparticles (NPs) and ZnO sol–gel (S‐G). The incorporation of ZnO NPs with high electron mobility facilitates efficient extraction of photogenerated electrons, thereby achieving improved ...

3D Printed Ordered Porous Architectures of Functional Metal Tellurides for Ultra High Mass‐Loaded Ammonium‐Ion Batteries

open access: yesAdvanced Energy Materials, EarlyView.
Aqueous ammonium‐ion batteries (AAIBs) are emerging as promising alternatives for next‐generation energy storage. To overcome the limited ion diffusion associated with ultrahigh mass‐loading electrodes, this work develops a 3D‐printed porous conductive electrode of metal‐telluride fabricated via selective laser melting technique.

FastCat: Autonomous Discovery of Multielement Layered Double Hydroxide Alloy Catalysts for Alkaline Oxygen Evolution Reaction

open access: yesAdvanced Intelligent Discovery, EarlyView.
A machine learning‐guided self‐driving laboratory screened over 500 nickel‐based layered double‐hydroxide catalysts for alkaline oxygen evolution. Out of the eight metals, the robot uncovered a quaternary Ni–Fe–Cr–Co catalysts requiring only 231 mV overpotential to reach 20 mA cm−2.
