Thickness Effect and Mesoscopic Character of the Metal Oxide Gas Sensing Nano-Thin Films

Abstract:

Article Preview

The characters of metal oxide gas sensing nano-thin films are studied. The formula of the dynamical thickness effect characteristic time is given. The relation of the sensitivity Sn and the film thickness l, the character of existing the optimum thickness, the character of the change of conductance activity energy with the film thickness are given also. The idea of diffusion reaction of gas sensing mechanism and the idea of mesoscopic effect in the nano-thin films are proposed.
