Anomalous Field-Induced Desorption of Cesium from a Quasi-Spherical Surface of a Carbon-Saturated Rhenium Crystal

Abstract

Investigation of the field-induced desorption of cesium atoms from the surface of rhenium crystal emitter carbon-saturated in benzene vapors showed that, after desorption from the surface, the process continues and there appears a contour of desorption around {10 $$\bar {1}$$ 1} and {1 $$\bar {1}$$ 00} faces that contracts toward the centers of faces with increasing field strength. This previously unreported anomalous behavior of the field-induced desorption is explained by the intercalation of cesium into graphite structures formed on the emitter surface.
