Enhanced field-emission from a mixture of carbon nanotubes, ZnO tetrapods and conductive particles

In the present paper, the field emission properties of mixture of carbon nanotubes, ZnO tetrapods and conductive particles is discussed. To improve the field-emission further, a field-emission cathode with special edge structure is proposed in this paper. In Figure 1, the silver cathode electrode is first coated on a glass substrate. Then, carbon nanotubes are deposited on the cathode electrode as field emitters. To enhance the edge field-emission, a special edge structure is used. To analyse the enhancement of field-emission performance by the ZnO tetrapods and conductive particles, the electron trajectories in different field-emission diode structures are compared.
