Abstract
Branched ZnO nanowires were synthesized using a three-step process: 1) synthesis of ZnO nanowires by the thermal evaporation of a mixture of ZnO and graphite powders on Au-coated C-plane sapphire substrates for 1 h, 2) deposition of Au on the as-synthesized ZnO nanowires, and 3) resumption of the thermal evaporation process for 10 min. The multiple-networked branched ZnO nanowire sensors exhibited far superior NO2 gas sensing properties than the unbranched nanowires. The origin of the enhanced NO2 gas sensing properties is also discussed.
