This work illustrates the sensing behavior of Zn-doped and undoped In2O3 nanowires toward pollutant gases. An enhanced sensor response to reducing gases (e.g. H2, CO and ethanol) from indium zinc oxide (IZO) nanowires in comparison to In2O3 nanowires is obtained. Zn-doping increases the oxygen vacan...
