[IEEE 2018 31st International Vacuum Nanoelectronics Conference (IVNC) - Kyoto, Japan (2018.7.9-2018.7.13)] 2018 31st International Vacuum Nanoelectronics Conference (IVNC) - The experiment study of double grid to enhance electron transmission in field emission

摘要： The high electrons interception rate of grid in field emission will lead to gas desorption, cathode emission drop, grid deformation,short circuit and so on which will greatly affect the reliability of the device. In this paper, the double grid structure is used to improve the electronic transmission of the grid. The experimental results show that the electron transmission can be improved effectively.
