Carbon vaporizes at a high temperature, which would destroy the silicon
barrier
you want to feed it through. (It is estimated to melt above 4500 deg K
<http://stinet.dtic.mil/oai/oai?verb=getRecord&metadataPrefix=html&identifier=ADA112977>).

If you want reactive carbon, it would be easier to start with a reactive
carbon-containing molecule, and arrange for it to decompose or react at the
site you want it too. Lasers could be used to cause or help the reaction.

I was thinking of some form of transport mechanism, but all i can think
off at the moment is to suspend carbon atoms until they reach a specific
site (the work zone, as it were,) and encourage them to react with the lasers.
If they prove to be ionised by a laser maybe the transport method could be
magnetic....

Silicon is not so rigid at this scale as Perry mentioned. There are
silicon-containing materials called zeolites, with interesting small holes
(<http://en.wikipedia.org/wiki/Zeolite>) and you are right that molecule-sized
holes can make interesting reactions occur (see
<http://www.che.caltech.edu/groups/med/catmat.html> for an overview).
Having small holes, makes them a bit delicate at higher temperatures though.

Fascinating things, i have only had a chance to skim through so far, but
thanks, Toby, for the interesting links :-)
I've noted the site stinet.dtic.mil for future browsing too.

So the problem is then to find the right molecules and the right sort of holes
and the right conditions for the reactions you want to happen.

And is proving to be much trickier than i imagined :-/
