Title

Nanocrystalline Sno Gas Sensors In View Of Surface Reactions And Modifications

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 crystalite size is less than ∼10 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.
