A nonequilibrium Green's function study of thermoelectric properties in single-walled carbon nanotubes
Jin-Wu Jiang, Jian-Sheng Wang, Baowen Li
The phonon and electron transport in single-walled carbon nanotubes (SWCNT) are investigated using the nonequilibrium Green's function approach. In zigzag SWCNT (, 0) with $mod(…
A universal exponential factor in the dimensional crossover from graphene to graphite
Jin-Wu Jiang, Jian-Sheng Wang
A universal exponential factor, , is disclosed for the dimensional crossover of few-layer graphene (FLG) from two-dimensional graphene to three-dimensional graphite. $γ_…
Isotopic effects on the thermal conductivity of graphene nanoribbons: localization mechanism
Jin-Wu Jiang, Jinghua Lan, Jian-Sheng Wang +1
Thermal conductivity of graphene nanoribbons (GNR) with length 106~Å and width 4.92~Å after isotopic doping is investigated by molecular dynamics with quantum correction. Two inter…
Self-repairing in single-walled carbon nanotubes by heat treatment
Jin-Wu Jiang, Jian-Sheng Wang
Structure transformation by heat treatment in single-walled carbon nanotubes (SWCNT) is investigated using molecular dynamics simulation. The critical temperature for the collapse…
Mechanism of phonon localized edge modes
Jin-Wu Jiang, Jian-Sheng Wang
The phonon localized edge modes are systematically studied, and two conditions are proposed for the existence of the localized edge modes: (I) coupling between different directions…
Topological effect on thermal conductivity in graphene
Jin-Wu Jiang, Jian-Sheng Wang, Baowen Li
The topological effect on thermal conductivity is investigated through the comparison among graphene nanoribbons, carbon nanotubes and the Mobius-like graphene strips (MGS), by mol…
