What is Modulated Chemical Doping of Individual Carbon Nanotubes about?

Modulation doping of a semiconducting single-walled carbon nanotube along its length leads to an intramolecular wire electronic device. The nanotube is doped __n__ -type for half of its length and __p__ -type for the other half. Electrostatic gating can tune the system into __p__ - __n__ junctions, causing it to exhibit rectifying characteristics or negative differential conductance. The system can also be tuned into __n__ -type, exhibiting single-electron charging and negative differential conductance at low temperatures. The low-temperature behavior is manifested by a quantum dot formed by chemical inhomogeneity along the tube.
