Pique the Geek 20120805: Yet More Carbon

Last time we finished our discussion of diamond, and now we move to what is pretty incorrectly called amorphous carbon.  Truly amorphous materials. like glass, have no true crystal structure (although there may be some local microstructures) that repeats regularly.

When used in the sense of carbon, only recently produced thin films of carbon are truly amorphous.  These are of research interest for the most part, although I would be quite surprised if practical uses are not found for them before long.

We shall discuss forms of carbon traditionally called amorphous even though they are not truly amorphous.  These include some of the most commonly encountered forms of carbon, and almost everyone has seen and touched at least a few examples.
