Fullerene and
carbon nanotubes are the most common nanostructures. There exist many methods
for the synthesis of these materials. Both possess superlative properties and
are good candidates for various potential applications. Conductivity property
of these materials depends upon the chirality and length of the specimen
material. Superconductivity phenomena were observed in many compounds of
fullerene. Superconductivity is a phenomenon where the material loses its
resistivity absolutely. In 1991, in Bell laboratories, a team lead by Hebard,
synthesized C-60 crystals with potassium which exhibited superconductivity
phenomena at 18 K. Later superconducting transition temperature of 33K was
achieved in Cs2RbC60.
In these materials, superconducting transition temperature can be
increased by increasing the radius of dopant alkali atoms. The process of
introducing alkali atoms into Carbon-60 is known as intercalation.
