Single Electron Dynamics in Liquid-Gated Two-Layer Silicon Nanowire Structures: Towards Biosensing with Enhanced Sensitivity

Abstract

We fabricated new types of nanowires that consist of two silicon layers with different doping concentrations. Fabricated structures demonstrate pronounced random telegraph signal fluctuations as a result of single electron dynamic processes. Liquid-gated nanowire transistor devices show advanced characteristics favorable for a new sensing approach based on single trap phenomena.
