We have realized gas sensor devices, which are based on a single SnO2-nanowire or a multiple SnO2-nanowire network
as gas sensing components and are very sensitive to the toxic gas H2S. The nanowires are fabricated in a two-step
atmospheric pressure synthesis process directly on the Si-chip by spray pyrolysis and subsequent annealing. Exposure of
the single SnO2-nanowire sensor H2S with a concentration of only 1.4 ppm decreases the resistance by ~ 30%, while the
multiple SnO2-nanowire network sensor exhibits a resistance decrease by ~ 90%. The nanowire sensors have
extraordinary sensitivity with resolution limit in the ppb range and are able to measure concentrations well below the
threshold limit value of 10 ppm. Due to their high performance the nanowire based sensors are basically suited for the
realization of smart gas sensing devices for personal safety issues as well as industrial applications.
