摘要
考虑到场穿透引起的逸出功变化，修正了高温超导体材料的场致发射电流密度公式和高温超导体材料的场致发射电子能量分布公式。当考虑到发射体表面的原子级不平整对电场的影响时，利用公式计算的结果与实验结果基本符合。
The high - temperature superconductor field electron emission is reviewed in this paper. The formula of field emission current density and field electron spectrum of HTSC material isdeduced according to chang of Fermi energy level in surface region and modifed in the case of atomically prominence in surface. Numberical smiulation is made. Its result is agreement with that of field electron emission experiment.
