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. The major element of this simulator is a modified Fowler-Nordheim 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.
