Electronic structures and three-dimensional effects of boron-doped carbon nanotubes
boron doping carbon nanotubes superconductivity density functional theory
2010/10/12
We study boron-doped carbon nanotubes by first-principles methods based on the density
functional theory. To discuss the possibility of superconductivity, we calculate the electronic
band structure ...
