摘要

我们观察到光子能量Ø为2.5 ~ 3.1 eV的可调波长低功率飞秒激光激发W(310)尖端产生的光辅助冷场发射。从(310)取向单晶发射器的顶点发射电流显示为线性依赖于入射激光功率，而有效功函数是由各自的光子能量减少。

Linear Femtosecond Tunable-Wavelength Photoassisted Cold Field Emission

We observe photoassisted cold field emission from a W(310) tip induced by tunable-wavelength low-power femtosecond laser excitation with photon energies Ø from 2.5 eV to 3.1 eV. The emission current from the apex of the (310)-oriented single-crystalline emitter is shown to linearly depend on incident laser power, while the effective work function is reduced by the respective photon energy.
