Abstract

In the study of field desorption of cesium from rhenium carburized in benzene vapors, it was found that after desorption of cesium from the surface, desorption continues and a desorption contour is formed around the faces (1100), which shrinks to the centers of the faces as the field strength increases. The previously unobserved anomalous behavior of the field desorption is explained using cesium intercalation in graphite structures formed on the surface of the emitter.
