Abstract

Alkaline-earth metal, Sr, was doped on multiwalled carbon nanotubes (MWNTs) by vapor phase reaction method. The tunneling electron microscopy, energy dispersive x ray, and Raman spectroscopy were studied for verifying the Sr doping on MWNT. The temperature-dependent resistivity [ρ (T)] and thermoelectric power [S (T)] were also performed for both pristine MWNT and Sr-doped MWNT (Sr-MWNT). ρ (T) of Sr-MWNT did not significantly change compared to pristine MWNT. However, S (T) of Sr-MWNT considerably changes, i.e., it shows n -type behavior in contrast to pristine MWNT. © 2008 American Institute of Physics.
