Ultrasmall Metal Clusters Act Metallic
Metal clusters with as few as three atoms have metallic character analogous to bulk metals, according to experiments done at Georgia Institute of Technology (Phys. Rev. Lett., DOI: 10.1103/physrevlett.106.043401). A classical metal is one that can’t support an internal electric field and therefore has no permanent electric dipole moment. Theoretical analysis had predicted that small clusters would show a dipole moment and therefore should not be considered metallic, even for a traditional metal . . .
