Alcohol sensors using gallium nitride (GaN) nanowires (NWs) functionalized with zinc oxide (ZnO) nanoparticles have been demonstrated. These sensors operate at room temperature, are fully recoverable, and demonstrate a response and recovery time on the order of 100 s. The sensing is assisted by UV light within the 215-400-nm band and with the intensity of 375 nW/cm(2) measured at 365 nm. The ability to functionalize an inactive NW surface, with analyte-specific active metal-oxide nanoparticles, makes this sensor technique suitable for fabricating multianalyte sensor arrays.
