Thermal conductivity of carbon nanoring linked graphene sheets: A molecular dynamics investigation

“…The velocity exchanging was performed every 100 fs. [22,23] The transferred heat is calculated by the accumulation of exchanged kinetic energy as:…”

Thermal conduction of one-dimensional carbon nanomaterials and nanoarchitectures

“…[4] As the building blocks for various engineering applications, low-dimensional (i.e., 1D and 2D) nanomaterials have received the most extensive attention. Researchers have studied the thermal transport properties of nanowires, [5,6] single-walled or multi-walled carbon nanotube, [7,8] BN, SiC, and Ge nanotubes. [9][10][11][12][13] It is found that the carbon nanotube (CNT) has a thermal conductivity as high as ~ 3,000-3,500 W/mk at room temperature.…”

Material properties dependent on the thermal transport in a cylindrical nanowire

“…In recent years, thermal properties associated with acoustic phonons in semiconductor nanostructures have attracted a great deal of attention. [1][2][3][4][5][6][7][8] Employing the Landauer formulation of transport theory, Rego et al [9] firstly predicted the existence of thermal conductance quantization, π 2 k 2 B T /3h, analogous to the well-known 2e 2 /h electronic conductance quantization, in the dielectric quantum wire with catenoid contacts between the wire and the reservoirs at low temperatures. This prediction has been verified by Schwab et al [10] Understanding thermal conductivity of the nanostructure is very critical to address power dissipation in a nanodevice, which is one of the important problems faced by current electronic miniaturization.…”
