Abstract

A gold nanoparticle necklace array spanning a ∼30-micrometer-wide channel shows a robust coulomb blockade effect at room temperature with a threshold of 1V in air. When this device is operated in the aqueous solution, a gain of ∼130 fold in conductance is obtained in electrochemical gating, significantly higher than other nanomaterial-based electrochemical transistors.
