- Title
Ionic current pulses upon field desorption of cesium from graphene on iridium.

Bernatskii, D.; Pavlov, V.
- Abstract
Pulses of Cs ion current upon field desorption in constant electric field from an iridium point coated with a graphene film have been detected. Pulses with durations of less than 0.1 s were observed upon sputter deposition of cesium atoms onto graphene followed by their removal from the surface. During the pulse, one could observe a flash on the field desorption microscope display occupying all area of the images of {001} and {111} facets. Possible mechanisms of the flash formation using models of cesium intercalation in the graphene layer and the yield of cesium atoms from under the film under the action of the applied electric field of the electric field have been considered.
