Abstract: The precursors of LaFeO3 were prepared by sol-gel method and nanocrystalline film of the LaFeO3 were obtained by a solid phase reaction at about 550℃ for 1 hour.The thicknesses of the nanocrystalline films are uniformly distributed, and their crystal sizes are 40-50 nm.Combining this thin film technology with planar technique of integrated circuit, we have developed NCF-OSFETgas sensor for the first time.This device not only has good sensitivity to ethanol, but also has excellent selectivity.
