Analysis of electron emission mechanism in surface conduction electron emission displays

It is confirmed that the cause of anode current in SEDs (surface conduction electron emission displays) is the inertial force of electron emitted from the cathode surface in the calculation of electron trajectory. In the fissure of sub-micron, most of electrons emitted from the area of the cathode edge flow into the coplanar anode, while some electrons are emitted into the display surface by the current ratio of $10^{-3}$. The later electrons are forced to fly into the display surface by the centrifugal force due to the curved electric field between top side surfaces near the fissure.
