FIG. 1.

Room temperature I-V characteristics from ZnO thin films of thickness 20 or 350 nm measured in air before and after coating with Pt.

FIG. 2.

Current as a function of time for Pt-coated ZnO thin films of different thickness cycled from to in to air ambient (top) and the change in current at fixed bias (0.5 V) when switching to the -containing ambient (bottom).

Image of FIG. 3.
FIG. 3.

Time dependence of current from Pt-coated ZnO nanorods and thin films nanorods as the gas ambient is switched from to 500 ppm in ; then to air for recovery.

Image of FIG. 4.
FIG. 4.

Change in current at fixed bias (0.5 V) when switching to the -containing ambient of either Pt-coated ZnO nanorods or thin films as the gas ambient is switched from to 500 ppm in ; then to air for recovery.
