TL;DR: The surface diffusion and adsorption of oxygen on tungsten have been studied by a field emission technique, by utilizing the high sticking coefficient, and negligible vapor pressure of O2 at 42-20°K as discussed by the authors.
Abstract: The surface diffusion and adsorption of oxygen on tungsten have been studied by a field emission technique, by utilizing the high sticking coefficient, and negligible vapor pressure of O2 at 42–20°K Three types of migration were noted At ∼27°K diffusion occurs with a sharp boundary and an activation energy Ed≈09 kcal This is believed to be migration of physically adsorbed O2 over the chemisorbed layer, with precipitation on the bare surface The distance traversed by the boundary was found to be limited by desorption above ∼40°K A study of this effect yielded an estimate of 23 kcal for the heat of adsorption, Ha, in the physisorbed layer At 400–500°K and high coverages, diffusion occurs within the monolayer with activation energies of 23–25 kcal Boundaries moving radially outward from the close‐packed faces are observed, and believed to result from precipitation of O atoms in trap sites on the rough regions of the surface At low coverages boundary free diffusion with Ed≃30 kcal is observed and i
