PROJECT TITLE :
UV-Assisted Alcohol Sensing With Zinc Oxide-Functionalized Gallium Nitride Nanowires
Alcohol sensors using gallium nitride (GaN) nanowires (NWs) functionalized with zinc oxide (ZnO) nanoparticles have been demonstrated. These sensors operate at room temperature, are absolutely recoverable, and demonstrate a response and recovery time on the order of one hundred s. The sensing is assisted by UV light-weight among the 215–400-nm band and with the intensity of 375 $hboxnW/cm^2$ measured at 365 nm. The flexibility to functionalize an inactive NW surface, with analyte-specific active metal–oxide nanoparticles, makes this sensor technique appropriate for fabricating multianalyte sensor arrays.
