Abstract:Surface roughness represents the measure of the irregularities on the surface
contributing to the local field enhancement. The traditional Fowler-Nordheim
equation established for perfectly planar surfaces is not suitable for
describing emission from rough surfaces. Instead, it is more appropriate to
use the equation that accounts for the field enhancement factor describing
the effect of the surface morphology. In superconducting radio frequency
cavities field emission may occur in the irises… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
