  • Abstract
    We have examined the adsorption of H2S on ZnO nanowires, nanotubes and facetted nanotubes using density functional theory calculations. Our results show that the gas-sensor reaction is dependent on nanostructure shape, gas concentration and reaction temperature. Functionalization of ZnO nanostructures changed the size of the band gap, which could be useful for altering their electrical and optical properties.
