The effect of carbon on the diffusion of cesium on the renium surface

Abstract

The diffusion of cesium over the rhenium surface and the rhenium surface coated with carbon was studied by methods of the field electron and desorption microscopy. The method of continuous field desorption was used, in which surface diffusion ensures the flow of the adsorbate to the desorption site. It was found that the carbon-coated surface undergoes intensive diffusion of cesium, while there is no diffusion on the rhenium surface.
