摘要：

The effects of K and Li deposition on the emission characteristics of Spindt-type thin-film field emission microcathode arrays [Spindt et al. J. Appl. Phys. 47, 5248 (1976)] (TFFEMC) with Mo tips are discussed. The amount by which each alkali metal lowered the effective work function of a TFFEMC is reported and compared to results of similar measurements performed with a clean Mo(100) surface. In addition, it is shown that the emission current is enhanced during exposure to K flux, even after a saturation coverage has been established. These results are interpreted with a model based on an excess K coverage produced during dosing, which enhances the overall emission of the array.
