First, high-quality and high-density SWNTs were synthesized on a quartz substrate by dip-coating of catalysts and alcohol CCVD. The cap of SWNTs was opened by annealing in dry air at 430~500 degree C for 30 min. Here, Raman scattering spectroscopy was performed to investigate damages introduced by the cap-opening process. Finally, fullerenes were doped into the SWNTs by annealing the substrate in fullerene vapor at 450~500 degree C for 2 days. By TEM observation, we have confirmed the encapsulation of fullerenes in the samples cap-opened above 450 degree C. We have also successfully fabricated FETs with Gd@C82-peapod channel synthesized directly on a SiO2/Si substrate by using the present method.
