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.
