Field Effects on Chemisorbed Films in Electron Emission Microscopy

Article metrics

Abstract

THE migration of surface atoms of tungsten under the influence of a high electric field is a well-established phenomenon1–3. In addition the migration of multilayers of adsorbed inert gases in the applied field necessary for field emission has been observed4. Strangely enough, the effect of the field on the gases commonly used as adsorbates, namely oxygen, nitrogen, hydrogen, carbon monoxide, etc., does not seem to have been investigated, although field-desorption5 and the migration of barium2 have been studied.
