Reconfigurable Mixed‐Dimensional Transistor With Semimetal CNT Contacts

Advanced Electronic Materials
Reconfigurable low‐dimensional devices are attractive for electronics in the post‐Moore era. However, their performance and function design are limited by the metal–semiconductor contacts for the Fermi level pinning and fixed Schottky barrier height (SBH)

A Dual‐Functional Electrolyte Additive for Highly Reversible Zinc‐Ion Batteries

Advanced Functional Materials, EarlyView.
This study introduces tetrabutylammonium bromide (TBAB) as a dual‐function additive for aqueous zinc‐ion batteries. TBAB disrupts the hydrogen‐bond network of water while TBA+ adsorbs on Zn to improve interfacial wettability and regulate Zn2+ flux, resulting in suppressed dendrite growth and parasitic reactions. This synergy extended the lifespan of Zn|
