1. A method of n-type doping a carbon nanotube, comprising:
providing a single carbon nanotube:
providing a film-like structure, wherein the film-like structure is a molybdenum disulfide film or a tungsten disulfide film; and
converting at least one portion of the carbon nanotube from a p-type doping to an n-type doping by covering the carbon nanotube with the film-like structure.
