Abstract
Ti modified ZnO nanowires (NW) film has been demonstrated as an excellent Nitrogen Dioxide (NO2) sensor. Herein, Ti acts as a sensitizer to improve the sensor response, and response kinetics of ZnO NW towards NO2. The sensor exhibited an enhanced response (Rg/Ra) of 7 at an optimum operating temperature of 200oC. The observed sensing characteristics are corroborated with the finding of work function measurements using Kelvin Probe Technique.
