I will talk about our recent work on advanced gating structures for nanowire transistors. The initial focus will be traditional oxide/metal-based formulations for making horizontal nanowire transistors with multiple, independent wrap-gate segments. I will then look at a more innovative materials approach using electron-beam processible polymer electrolytes as a simple way to enact wrap-gating via mobile ions in the polymer electrolyte. These can be used to enact external 'ionic' doping of nanowires for low temperature applications and be used to build hybrid ionic-electronic circuit elements like inverters with potential for low frequency ion-to-electron transduction for biological sensing applications.
