Abstract
The gas-sensing mechanism of an n-type semiconductor (tin dioxide) gas sensor is reviewed in this paper It is demonstrated that very high sensitivity can be obtained only when the crystallite size is less than similar to10 nm. Various mechanisms involving the surface and the bulk modifications of the semiconductor oxide gas sensors are discussed to improve the gas sensitivity. Current challenges and problems in nanocrystalline oxide gas sensors are also presented.
