Effect of Aliphatic and Aromatic Rings on Cold Field Emission Behavior

ecent studies have revealed promising cold field emission (CFE) behavior in composite metal insulator, metal-graphite, and insulator-graphite electron sources, particularly when coatings include aliphatic or aromatic organic rings, such as graphene or benzene. These molecular configurations significantly influence the emitted electron beam, resulting in performance distinct from that observed in previous studies. This project applies a novel in-situ adaptation of Forbes field emission orthodoxy testing, combined with noise spectroscopy, to investigate CFE properties and current stability of high-potential coating materials—critical for advancing vacuum nano/microelectronics.
