  4. Abstract:
  5. Phosphorene is a new two-dimensional material that has great potentials in Nano electronic application, so it has attracted more researchers' attention nowadays. Indeed, phosphorene is an interesting material in gas sensing, due to its high surface-to-volume ratio and its carrier mobility. Many studies have been reported on phosphorene gas sensing, but there is not enough study on analytical modeling of phosphorene gas sensing properties. In this research, by adopting data from experimental NO2-based gas sensor, an analytical model of the phosphorene gas sensing behavior is presented. Then, the experimental results of NO2 gas sensing are compared with the proposed model and acceptable agreement is reported. This new model is adapted to predict phosphorene gas sensing performance in higher NO2 gas concentrations, which demonstrates, linear relation is established in higher concentrations same as lower ppb NO2 gas concentration. So, we have predicted the result of NO2 gas sensing for higher concentration based on experimental sensing. © 2019 World Scientific Publishing Company
