Abstract
ZnO film was fabricated using successive ionic layer adsorption reaction (SILAR) with varying concentrations of 0.1M, 0.15M and 0.2M and varying number of dippings of 50, 100, 150, 200 using an automated dipping machine. Scanning Electron Microscopy (SEM) revealed a uniform _lm for the sample grown using 0.1M concentration of sodium zincate bath and 200 dippings. With these parameters, Pd was used to sensitize the film. IV curve shows that the resistivity of the film decreases when mixed with Pd. Films with and without Pd was exposed to the gas. Both responded to the gas but ZnO film with Pd (136.23%) shows higher sensitivity than ZnO without Pd (58.67%).
