Abstract A study of the adsorption of oxygen on steel at room temperature has been performed in an ultra-high-vacuum system with oxygen in the pressure range from 10−9 to 10−4 Torr. Ellipsometry, surface potential difference, and Auger spectroscopy were the surface techniques used. The surface of the steel was cleaned by Cs+ and Ar+ bombardment. The mechanism of the adsorption process is postulated to involve adsorption of molecular oxygen, followed by dissociation and chemisorption of atomic oxygen to form one monolayer. Further adsorption on top of this monolayer is associated with a place-exchange process to produce multilayers of oxide.
