Experiment and Theory for the Thickness Effect of Nano Metal Oxide Gas Sensing Thin Film  Dynamic Thickness Effect and Theory of Diffusion Reaction

The rule of characteristic time varies with film thickness, gas concentration is given by experiment results. The diffusion reaction model of conductance response for porous gas sensing thin film is proposed; with solution and non-dimensional analyze the reaction diffusion equation, the rule of character time can be yielded. Using the method of combination of theoretical and experimental, the surface adsorption exponent gamma and adsorbing energy Ea are discussed
