Abstract

original image

Part of an enhanced-mode electrolyte-gated nanowire channel metal oxide semiconductor field-effect transistor (MOSFET) is illustrated. As reported by Subho Dasgupta and co-workers on page 1750, the complete nanowire and a part of the in-plane gate electrode are covered with a printed droplet of composite solid polymer electrolyte, working as a dielectric. A positive gate bias attracts cations (Li+) towards the nanowire channel resulting in accumulation of charge carriers and driving it to the conducting (ON) state.
