Abstract

A study is presented of the nature of ordered phases of various gases adsorbed on an isolated carbon nanotube. Because the spacing between neighboring adsorption sites depends on the tube's radius R, the equilibrium structure of the ground state is predicted to differ from that observed on planar graphite. Results for this structure are presented for the inert gases and hydrogen as a function of R for zigzag nanotubes.
