The radial breathing-like mode of the collapsed Single-walled carbon nanotube bundle under hydrostatic pressure
Gang Wu, Xiaoping Yang, Jinming Dong
Using the first principles calculations we have studied the vibrational modes and Raman spectra of a (10, 10) single-walled carbon nanotube (SWNT) bundle under hydrostatic pressure…
Ferromagnetism of an all-carbon composite composed of a carbon nanowire nside a single-walled carbon nanotube
Xiaoping Yang, Jinming Dong
Using the first-principles spin density functional approach, we have studied magnetism of a new type of all-carbon nanomaterials, i.e., the carbon nanowires inserted into the singl…
Structural transformations of double-walled carbon nanotube bundle under hydrostatic pressure
Xiaoping Yang, Gang Wu, Jinming Dong
Three kinds of the response mechanisms to the external pressure have been found for double-walled carbon nanotube (DWNT) bundle, depending strongly on their average radius and symm…
Ferroelectricity of Ice Nanotubes inside Carbon Nanotubes
Chuanfu Luo, Wei Fa, Jinming Dong
We report that ice nanotubes with odd number of side faces inside carbon nanotubes exhibit spontaneous electric polarization along its axes direction by using molecular dynamics si…
Non-left-handed transmission and bianisotropic effect in a [pi]-shaped metallic metamaterials
Z. G. Dong, S. Y. Lei, Q. Li +5
A [pi]-shaped metallic metamaterial (geometrically, a combination medium of C-shaped resonators and continuous wires) is proposed to numerically investigate its transmission band n…
