Original Abstract

This initial study aims to explore the topic of thin barrier layers for single tip cold field emitters. The experiment and measurements have been conducted in ultra-high vacuum field electron microscope. Additionally, micrographs of the emitter were obtained using scanning electron micro- scope. The performance of the emitter was evaluated using orthodoxy test and Murphy-Good plots, which can give more complete picture of emitter changes during field emission.
