Abstract: The size-dependent metal to nonmetal transition in
metal nanoparticles has been investigated using photoelectron and tunneling
spectroscopic techniques. Metal nanoparticles capped by thiols are shown
to organize into ordered 2D and 3D structures. Single-walled nanotubes
and aligned carbon nanotube bundles have been synthesized by controlling
the size of metal nanoparticles produced in situ during the pyrolysis
of precursors. Nanowires of gold and other metals have been produced
in the capillaries of the single-walled nanotubes.
