On the metallic behavior of Co clusters

The role of structure in the nonmetal-metal transition of Co clusters is investigated by performing calculations for different symmetries: hexahedral, octahedral and decahedral. This transition occurs when the density of states at the Fermi level exceeds l/kBT and the discrete energy levels begin to...
