Electrostatic and chemical doping of C60-filled nanotubes

ORAL

Abstract

C60-filled nanotubes, known as fullerene peapods, have attracted considerably interest for many years not only because of their peculiar hybrid structures but also due to their anticipated unique electronic properties and potential applications, such as memory effects and high temperature superconductivity. However, the superconducting or even truly metallic behavior has not yet been achieved. In this study, we use both the electrostatic and chemical methods to effectively dope the C60-filled nanotubes and modulate their transport properties. TEM characterization and low temperature transport results on these doped samples will be presented.
