Experimentalists have shown that carbon nanotubes are among the
most electrically conductive materials known. It also has been
shown that individual carbon nanotube molecules can be used to
make electrical switches and wires. Building upon these
discoveries, this presentation first will display and discuss
explicit novel designs for electronic digital logic circuits
that might be made from such carbon nanotube switches and wires.
That is, it will be shown how carbon nanotubes might be employed
to design a carbon-based molecular-scale electronic digital
computer. To implement these designs, though, it is necessary to
have new techniques in nanotube chemistry that will permit the
mass fabrication of precisely designed nanostructures. To that
end, the presenters also will discuss a new chemical technique
that has been designed for this purpose. Computer simulations of
this macroscopically controlled nanofabrication technique
indicate that it should produce nanopatterned circuit-like
carbon structures in quantity
