SHORT NANOTUBES OR BIG MOLECULES?: THE CONCEPT OF MINIMAL LENGTH
We have studied the problem of what must be the minimal length of a nanotube with a given diameter to reasonably assert that its electronic properties can be extrapolated to longer structures. For this purpose the variation of the electronic chemical potential (ECP) was plotted against the number of...
