AdsorptionThe molecular adsorption of nitrogen on Fe films was studied between 77 K and 273 K. By means of a combined measurement of adsorption isotherms, changes in resistance, changes in work function and replacement processes using 14N2 and lSN2 it was possible to determine the regimes of the u-, 7-, and 6-states. Films annealed at about 320 K exhibit an adsorption behaviour very similar to that of Fe(ll1) single crystal surfaces.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
