Abstract
Simulation of sensor signal based on the ZnO work function for NO2 gas has been conducted. This research is aimed at approaching the experiment results of nitrogen dioxide (NO2) gas detection using the ZnO sensor. This study uses three reactions i.e., adsorption�desorption of O2 (oxygen), adsorption-desorption of NO2, and the reaction of O2 and NO2 on ZnO. This simulation has optimized 12 parameter values that are responsible for those reactions. After the optimized values were obtained, the final simulation was reached. The final simulation still cannot perfectly fit the experiment results because of the number of reactions which are used still three reactions. It is predicted, if it is used much more reactions, the simulation could be the same as the experiment results. Although this simulation is still not same as the experiment result, it has a trend as the experiment result. The last result of this model i.e. it can predict the coverage of O atom, O2 molecule, and NO2 molecule.
