Voltage Gated Ion Entry Into Two‐dimensional Angstrom‐Scale Channels

Advanced Functional Materials, EarlyView.
We demonstrate voltage‐gated ion transport through artificial Å‐scale slit channels (∼4 Å high) formed by van der Waals assembly of 2D materials. At low electric fields, ions are excluded while water permeates. Above a threshold voltage, nonlinear hysteretic conduction emerges, driven by ion dehydration and concentration‐dependent barriers, mimicking ...
