A theoretical investigation of the interaction between H,Li, Na,K, and fullerenes

We studied the interaction between H, Li, Na, and K with one and two C₆₀ molecules using unrestricted Hartree–Fock (UHF) methods. We investigated the effects of distances between the doping atoms and the C₆₀ clusters, total charges, interaction energies, stabilities, HOMO‐LUMO energy differences, charge distribution, and potential energy surfaces. The effect of each doping atom was analyzed and potential technological applications discussed. © 2004 Wiley Periodicals, Inc. Int J Quantum Chem, 2005
