On temperature dependence of ion yield in electron stimulated desorption

Analytical expression for the temperature coefficient of yield of ions, desorbed by reverse mechanism, was obtained in the framework of relaxation model of electron stimulated desorption. Thermal oscillations of adsorbed atoms with temperature dependent amplitude, were considered. Results of calculation, performed for desorption of Na+ ions from silicon monolayer surface, precipitated on tungsten substrate, correspond satisfactorily with the experiment
