Abstract: Electron-stimulated desorption of cesium atoms from monolayer graphene on iridium has been observed at 160 K and 300 K. Migration processes have been shown to be frozen at 160 K, and cesium atoms to be located only at the graphene surface. At 300 K, due to intercalation an additional layer of cesium atoms is produced and located under the graphene layer. We believe that observed electron-stimulated desorption of cesium atoms is due to the non-metal nature of the adsorbed graphene film independently on the metal nature under it: iridium or cesium.
Keywords: electron-stimulated desorption, graphene, intercalation.
