A Water-Gate Organic Field-Effect Transistor

High‐dielectric‐constant insulators, organic monolayers, and electrolytes have been successfully used to generate organic field‐effect transistors operating at low voltages.

Summary:High‐dielectric‐constant insulators, organic monolayers, and electrolytes have been successfully used to generate organic field‐effect transistors operating at low voltages. Here, we report on a device gated with pure water. By replacing the gate dielectric by a simple water droplet, we produce a transistor that entirely operates in the field‐effect mode of operation at voltages lower than 1 V. This result creates opportunities for sensor applications using water‐gated devices as transducing medium.
