Experiments and Simulation of electron emission form screen printed nanostructure ZnO film

The Nano-ZnO and nanographite was mixed with other vehicles to form paste. The mixture of nanographite, sintering and anneal treatment process was performed to intentionally improve the electron tunneling and electron emission of screen printed Nano-ZnO film. According to the Fowelr-Nordheim equation, the Matlab simulation programming model was established. Compared the 2D and 3D graphics obtained through the simulation to the curves of the experiments, the direction and shape of the curves is basically similar and confirm the results of experiments.
