Sensing extremely limited H₂ contents by Pd nanogap connected to an amorphous InGaZnO thin-film transistor.

Abstract

A palladium (Pd) nanogap-based thin-film has been connected to an electrically stable amorphous InGaZnO thin-film transistor, to form a hydrogen sensor demonstrating a dramatic sensing capability. As a result of the Pd connection to the transistor source, our sensor circuit greatly enhances the hydrogen-induced signal and sensing speed in the sense of… (More)
