Abstract

This work aims to investigate on the electrical, optical and gas-sensing properties of zinc oxide-based nano-wires (nwZnO) deposited on a crystalline silicon (c-Si) wafer. In particular, a comparison between the less efficient heat treatment for the analyte desorption and the photo-enhanced response will be investigated and discussed for NO₂ gas flows.
