[sci.nanotech] Molecular transistors

In the July 12 Science News, there is a report of a step forward in the
attempt to construct molecular electronic devices (basically transistors
from what I could tell, but they didn't call them that).

A couple years ago, some scientist at IBM designed a molecule which
should function about the same as a transistor.  This report describes
the construction of a similar molecule by a scientist at U of S.
Carolina.  The key difference seems to be that the ideal molecule has a
silicon atom in its center and this one has a carbon there.

The molecule is about 3 orders of magnitude smaller than what can
currently be done on chips.  However, some researchers think that
quantum effects will keep the molecule from functioning as advertised.
