三维热场致发射模型的数值模拟与研究
Numerical simulation and study of three-dimensional thermal field emission
摘要
Abstract
In this paper, we study the basic theory of field emission, thermionic emission and the thermal field emission, derive their current density formula, the initial distribution of the particles and their initial momentum. And then we achieve a field emission model, thermionic emission model and thermal field emission model on the basis of FDTD-PIC algorithm software. Finally, we verify its correctness using a wedge-shaped-cathode device.关键词
