C₆₀ Adsorbed on Ni(111) and Co(0001) Surfaces
Résumé
Carbon-60 molecules were deposited on the fcc Ni(111) surface and, for the first time, the surface of bulk hcp Co(0001) and measured using low-energy electron di↵raction and scanning tunneling microscopy. An adlayer with predominantly (4 ⇥ 4) domains is formed in each case. Other domains exemplify chiral epitaxial degeneracy. Annealing produces films with bright and dim molecules, with di↵ering details per substrate. For C 60 adsorption atop Ni(111), annealing results not only in vacancy formation beneath dim molecules, but also in adatom nucleation below bright molecules.
