Temperature dependent response of ZnO based H2S gas sensor
Temperature programming is one of the techniques to achieve selectivity with metal oxide semiconductor (MOS) gas sensors. Here, we report a study on the response of ZnO nanostructures based H2S sensor at different temperatures. It was observed that the response didn’t exhibit the same behavior at all concentrations with increase in temperature. It can be attributed to adsorbed oxygen molecules, adsorption-desorption rate and number of surface charge carriers, which vary with temperature. This variation in sensor response with temperature for different concentration can be useful in developing single sensor based electronic nose to detect multiple gases selectively.
