| Research Abstract |
Electronic structures of impurity-doped carbon nanotubes were studied systematically in order to discuss the application to semiconductor device and the possibility of superconductivity. We discussed impurity levels of boron- or nitrogen-doped nanotubes, the doping rate dependence of the electronic structures, and the effect of three-dimensionality in multi-walled nanotubes. Furthermore, to discuss the detailed physical properties, we developed the method using Green function theory based on the density functional theory.
