Non-equilibrium thermal transport simulation of conical carbon nanofibers

抄録

Using non-equilibrium molecular dynamics, we study the thermal transport properties of conical carbon nanofibers, comparing with single-walled carbon nanotubes and graphene nanoribbons. Our results predict that the conical nanofibers have at least a two-order of magnitude smaller thermal conductivity. We then predict the potential applicability of conical-helix carbon nanofibers to nanoscale thermoelectric devices.
