The study of Density Functional Theory for dispersion relation in Carbon nanotube with dielectric medium in a coupling modeBy RASHIMI YADAV, Daya Shanker, Utkarsh Kumar Sharma
Abstract: The author shall study the excitation of Surface Plasmon and Phonon on cylindrical polar semiconducting material. The possibility of their interaction has been discussed with the help of dispersion relation for the dual mode of CNT by using inherent properties of the dielectric interface in dual mode. The phonon dispersion relation of the CNT is calculated by large supercells containing an isolated nanotube, Density functional Theory, and plane wave basis …

Study of Phase Velocity and Magneto Plasmon Dispersion on the Surface of Carbon Nanotubes in Low Energy StateBy RASHIMI YADAV, Daya Shanker
Abstract: Several authors have worked on theoretical and experimental plasmon excitations. The researchers have been studying the dispersion relation of magneto plasmon in the low energy state on a cylindrical surface of carbon nanotube obtained with the help of linear-angular momentum transfer. Here, we demonstrate the Dirac-like Hamiltonian equation for carbon nanotubes in the presence and absence of a parallel applied magnetic field. We assume the cylindrical carbon nanotube is infinitesimally …
