Quantum change for nanotubes
A metallic carbon nanotube can be made into a semiconductor and vice versa when a magnetic field is combined with a little quantum mechanics. The electronic properties of a carbon nanotube, for example, depend on its chirality, which, in turn, depends on the direction in which the graphene sheet has been rolled up to form the nanotube. About two-thirds of nanotubes are semiconductors, and the remaining third are metals.
