Features of field desorption of sodium and cesium from the surface of a carbonized rhenium field emitter

Abstract:
We used field emission microscopy to study the field desorption of sodium and cesium atoms from a rhenium field emitter precarbonized in benzene vapor. The dependences of the ion currents of sodium and cesium on the voltage applied to the field emitter differ. The difference in the ion current dependences is explained by the formation of multilayer graphene on the crystalline surface of a rhenium field emitter in the regions of low-index faces and its intercalation by alkali metal atoms with different ionization potentials and different atomic and ionic radii.
Keywords:
