Controlling the doping level of double-walled carbon nanotubes by using aromatic hydrocarbon complexes

Abstract

The level of potassium doping in double-walled carbon nanotubes is controlled by using the potassium–aromatic hydrocarbon (AH) complexes. The concentration of doping increase when the large AH molecule complex is delivered. The crystalline perfection is also affected by the degree of K-doping.
