Atomic hydrogen is an active species that interacts with the surface of a carbon nanotube. We investigated the adsorption of atomic hydrogen on the cap of a carbon nanotube using field electron emission. We observed unusually stable adsorption sites on a field electron emission image of the cap after atomic hydrogen exposure. The adsorption sites on the cap were analyzed by comparing with a clean surface image of the cap, and found to be dependent on the structure of adsorbing hydrogen atoms, probably monomer or dimer.
