ABSTRACT:
A nanotube forming method includes growing a plurality of nanotubes to an intermediate length that is deterministic of nanotube intrinsic conductivity. Individual nanotubes exhibit an effective conductivity, which varies among the plurality of nanotubes. The method includes completing growth of nanotubes exhibiting effective conductivities inside a selected range without completing growth of nanotubes exhibiting effective conductivities outside the selected range. Before completing nanotube growth, the method may further include stopping nanotube growth and screening out nanotubes exhibiting conductivities outside the selected range. The screening out of nanotubes may include deforming or masking nanotubes exhibiting conductivities outside the selected range. Deforming nanotubes may include applying a potential.
