Abstract
Aligned nanowire arrays were coated with semiconductor shell layers, and optionally with noble metal nanoparticles for use as three dimensional gas sensors. The sensors show room-temperature responses to low concentrations of various gases. Arrays containing different sensor types can discriminate among different gases, based upon changes in conductivity and response times.
