Riassunto
Thermally-driven field-effect control of a nanowire (NW)-based device is achieved by exploiting thermodiffusion phenomena (Soret effect) in a droplet of electrolyte coupled to the NW, taking advantage of the electric double-layer (EDL) forming at the interface between the electrolyte and the NW. Device operation as EDL NW field-effect transistor is preliminary reported. Thermally-driven modulation of the electronic transport in the NW device is observed, characterized in its full parameter space at 300 K and qualitatively rationalized.
