Abstract: We have studied the concentration dependences of electron-stimulated desorption (ESD) of Cs , Na , Sm , and Eu atoms upon their adsorption on nonmetallic layers of films grown on W substrate. It has been found that ESD processes occur at the adlayer – nonmetallic substrate interface.  It has been also shown that reducing the ESD yield beyond one monolayer is due to a decrease in the number of exciting ESD electrons reaching the interface.

Keywords: electron-stimulated desorption, adsorption, alkali metals, rare-earth metals, gold, intermetallic compounds
