Thermal conductivity of configurable two-dimensional carbon nanotube architecture and strain modulation
HF Zhan and G Zhang and JM Bell and YT Gu, APPLIED PHYSICS LETTERS, 105, 153105 (2014).
We reported the thermal conductivity of the two-dimensional carbon nanotube (CNT)-based architecture, which can be constructed through welding of single-wall CNTs by electron beam. Using large-scale nonequilibrium molecular dynamics simulations, the thermal conductivity is found to vary with different junction types due to their different phonon scatterings at the junction. The strong length and strain dependence of the thermal conductivity suggests an effective avenue to tune the thermal transport properties of the CNT-based architecture, benefiting the design of nanoscale thermal rectifiers or phonon engineering.
