Numerical Simulation of Field Emission in the Surface Conduction Electron-Emitter Display

Abstract

We employ a three-dimensional (3D) particle-in-cell method coupling with finitedifference time domain scheme to simulate the electron emission in surface conduction electron-emitter displays (SEDs). This computational technique includes the space charge effects automatically. We thus explore the conducting mechanism, the emission efficiency, and the current density distribution on the anode plate with one field emission emitter.
