Carbon nanotube production is accomplished by either chemical, physical, or other processes (Rafique and Iqbal 2011). Chemical vapor deposition (CVD) is a method for large-scale production of CNT, involving use of a hydrocarbon gas such as ethylene, methane, or acetylene; a process gas, either ammonia, nitrogen, or hydrogen; and a substrate

Guinea, F. Abstract. The nonhomogeneity of the charge distribution in a carbon nanotube leads to the formation of an excitonic resonance, in a way similar to the one observed in x-ray absorption in metals. As a result, a positive anomaly at low bias appears in the tunneling density of states. This effect depends on the screening of the electron

A mixture of single-walled carbon nanotubes and a special copper complex is deposited between the electrodes. The copper complexes bind tightly to the carbon nanotubes. When the sensor comes into contact with ethylene, the ethylene binds to the copper complex, weakening the bond between the copper complex and the carbon nanotube.
