Tungsten oxide nanowires were synthetized by thermal oxidation in vacuum, using a custom tubular furnace, adding niobium in the growth process to evaluate the influence of niobium in the conductometric response towards hydrogen gas.Samples were characterized by XRD and Raman spectroscopy, to confirm the crystalline structure of the material.The conductometric response of fabricated sensors was evaluated...
One of the most promising architectures of third generation solar cells is integration of single crystalline nanowires as electron transporters in anodes of electrochemical cells. The nanowire-based cells aim at significantly increase cell efficiency thanks to the higher mobility of electrons along the single crystalline lattice of the nanowires with respect to traditional polycrystalline networks,...
Interest in nanowires of semiconducting oxides is exponentially grown in the last years, due to their attracting potential applications in electronic, optical and sensor field. We have focused our attention on the sensing properties of metal oxide nanowires as conductometric and optical gas sensors and conductometric DNA sensor. Single crystal nanostructures were synthesized with the aim of exploring...
