    Room Temperature Gas Sensing with Ultrathin Au Nanowires
    Author(s): Lal NLal N

    One-dimensional nanostructures are of particular interest in nanoelectronics because of the ease with which they can be utilized in fabricating nanodevices where their long axis facilitates contact to the structure, while the short axis preserves the quantized nature of electronic levels. It is therefore desirable to synthesize precisely controlled semiconductor and metal nanowires to study their properties. With much advancement achieved in producing high quality and appreciably controlled semiconductor nanowires, approaches to precisely control the dimensions of metal nanowires still needs to be explored. Here, we have investigated room-temperature sensing properties of these gold nanowires for hydrogen, ethanol and NH3. The sensitivity and selectivity of the wires for sensing different gases are explored. The sensing devices were fabricated by drop-casting the nanowire dispersion o.. Read More»
