Body-centered tetragonal C4: a viable sp3 carbon allotrope.
TL;DR: In this article, the electronic, vibrational and structural properties of bct C4, a new form of crystalline sp{3} carbon recently found in molecular dynamics simulations of carbon nanotubes under pressure, were investigated by first principles.
Journal ArticleDOI
Energetics and electronic structures of encapsulated C60 in a carbon nanotube.
TL;DR: Calculated total-energy electronic structure calculations that provide energetics of encapsulation of C60 in the carbon nanotube and electronic structures of the resulting carbon peapods find that the C(60)@(10,10) is a metal with multicarriers each of which distributes either along the nanotubes or on the C60 chain.
Journal ArticleDOI
Formation, stabilities, and electronic properties of nitrogen defects in graphene
Yoshitaka Fujimoto,Susumu Saito +1 more
TL;DR: In this article, the authors investigated nitrogen-doping effects in a graphene sheet using a first-principles electronic-structure study in the framework of density-functional theory, and they found that the nitrogen-impurity states appear around the Fermi level as either acceptorlike or donorlike states, depending on the atomic geometries of the nitrogen impurities in graphene.

Journal ArticleDOI
Effect of intertube coupling on the electronic structure of carbon nanotube ropes
TL;DR: In this paper, structural and electronic properties of an ordered bundle of (10,10) carbon nanotubes were analyzed and it was shown that inter-tube coupling causes an additional band dispersion of 0.2 \mathrm{eV} and opens up a pseudogap of the same magnitude at the same time.
