Some Measurements of Adsorption of Nitrogen and Oxygen on a (0001) Titanium Surface Using Low-Energy Electron Diffraction

Abstract
Both nitrogen and oxygen chemisorb on the clean (0001) surface of titanium in crystalline monolayers having the same hexagonal symmetry and lattice constant as that of the titaniumsurface, but with different distances between the surfacetitanium plane and the gas planes. Adsorption as a function of exposure was determined for both gases. An average sticking coefficient for nitrogen at room temperature of about 1.8×10—5 was obtained.
