Simulation of Geometric Effects on Double-Gate Field Emission Devices

Abstract

We report a study of the circular-shaped and rectangular-shaped focus-gate Field Emission Devices (FED) structure. In this work, we have developed a simulator of FED based on the Finite Difference Method (FDM). The major element of this simulator is a modified Fowler-Nordheim (F-N) field emission model. We evaluate the performances of the circular-shaped and rectangular-shaped focus-gate FED structures by using this simulator. Results reveal that the circular-shaped focus-gate FED structure has more collector current. Also the focusing characteristics of electron beam are improved.
