Investigation of structural and electronic transport properties of graphene and graphane using maximally localized Wannier functions

Abstract

Effect of negatively charged dust on resistive instability corresponding to the electrostatic wave is investigated in a Hall thruster plasma when this purely azimuthal wave is tilted and strong axial component of wave vector is developed. Analytical calculations are done to obtain the relevant dispersion equation, which is solved numerically to investigate the growth rate of the instability. The magnitude of the growth rate in the plasma having dust particles is found to be much smaller than the case of pure plasma. However, the instability grows faster for the increasing dust density and the higher charge on the dust particles. The higher magnetic field is also found to support the instability.

Microscopically inhomogeneous electronic and material properties arising during thermal and plasma CVD of graphene

“…The I(V) measurements also do not show any non-zero band gap material involved in the current transport (which would indicate hydrogenated graphene). 41,42 This means that the lower conductivity of the plasma CVD graphene is probably not caused by graphene hydrogenation, and it is most likely related to different nucleation and an early stage of graphene growth under plasma conditions.…”

Investigation on electronic transport property of cerium nitride nanoribbon-based molecular device: a first-principles study

“…The electron-electron interactions of the molecules are estimated with GGA through Perdew-Burke-Ernzerhof (PBE) exchange correlation [12,13]. In the present work, GGA-PPE functional is used throughout the calculation [14][15][16][17]. The optimization of the molecular geometry is taken into picture by decreasing the atomic forces of the atoms, which is smaller than 0.05 eV/Å .…”
