Abstract : Novelty In this work, we study the effect of n-p heterojunctions in metal oxides (MOX) gas sensors, and particularly on their gas sensitivity and relative humidity dependence for indoor air quality applications. This effect depends on the relative proportion of MOX in the mixture. This study was achieved in order to build a MOX gas sensor that overcomes the effects of humidity variations and to improve the overall sensitivity of MOS gas sensors.
