Synthesis of ZnO nanowires and impacts of their orientation and defects on gas sensing properties

ZnO nanowires (NWs) oriented in three different directions were synthesized via the vapor-liquid-solid technique over c-, r- and a-plane sapphire substrates. Gas sensing properties of these samples against reducing and oxidizing gases were examined. ZnO NWs grown on the c-plane substrate showed the...
