Patent ID: 7011884

Claim:
A carbon nanotube device, the device comprising: a carbon nanotube core having a diameter from approximately 1 nanometer to approximately 100 nanometers, the carbon nanotube core having a first end and a second end; a graphitic outer layer integrally attached to the carbon nanotube core, the graphitic outer layer having a diameter of approximately 1 micrometer to approximately 10 micrometers, the graphitic outer layer having a first end and a second end, the first and the second ends of the graphitic outer layer completely encompassing the first and the second ends of the carbon nanotube core; and a mechanically breakable portion of the second end of the graphitic outer layer, wherein the portion of the second end of the graphitic outer layer being mechanically broken off exposes and reveals a portion of the second end of the nanotube core.
