N2 - Polyaniline (PANI)-intercalated MoO3 ((PANI)xMoO 3), which is a conventional layered organic/MoO3 hybrid, as a gas sensor has a resistance drift problem, which should be solved in order to realize practical applicable gas sensing devices. In this analytical study, XPS studies reveal that the resistance drift is caused by adsorbing and desorbing oxygen molecules from the atmosphere. The adsorption of enough oxygen molecules by annealing in air at a higher temperature than operating temperature can reduce the resistance drift phenomena.
