Electrostatic Control of the Thermoelectric Figure of Merit in Ion‐Gated Nanotransistors

Semiconductor nanostructures have raised much hope for the implementation of high‐performance thermoelectric generators. Indeed, they are expected to make available reduced thermal conductivity without a heavy trade‐off on electrical conductivity, a key requirement to optimize the thermoelectric figure of merit. Here, a novel nanodevice architecture is presented in which ionic liquids are employed as thermally‐insulating gate dielectrics. These...
