  Controlled Synthesis of Copper Oxide Nanowires

The objectives of this research are to synthesize copper oxide nanowires (NWs) with controlled properties and to explore a novel sensing platform of a single CuO NW coated with discrete nanoparticles for miniaturized gas and photonic sensors with superior performance. Specific goals of the project are: 1) Control of the CuO NW structure, morphology, and electronic properties by controlling the oxidative environment during the NW growth; 2) Rapid growth of long CuO nanowires from nanocrystalline copper, produced through the surface mechanical attrition treatment (SMAT) of ordinary copper substrates; 3) Fabrication, characterization, and device packaging of single CuO NW sensors with enhanced gas and photon sensing properties through decorating NW surfaces with nanoparticles. Copper oxide is a very new material for nanowires that's cheap and easy to manipulate and package into a micro-template targeting gas and photon sensing.
