- Abstract
Controlled doping of carbon nanotubes is elemental for
their electronic applications. Here we report an approach to tune the
polarity and degree of doping of single-walled carbon nanotubes via
filling with nickelocene followed by encapsulated reactions. Using
Raman, photoemission spectroscopy and transmission electron microscopy,
we show that nickelocene molecules transform into nickel carbides,
nickel and inner carbon nanotubes with reaction temperatures as low as
250 °C. The doping efficiency is determined for each chemical component.
Synchronous charge transfer among the molecular components allows
bipolar doping of the carbon nanotubes to be achieved in a broad range
of ±0.0012 e− per carbon.
