摘要：

The thermal conductivity of carbon nanotubes with geometric variations of doped nitrogen is investigated The phenomenon of thermal rectification shows that the heat transport is preferably in one direction The asymmetric heat transport of the triangular single-nitrogen doped carbon nanotubes (SNDCNTs) is larger than that of the parallel various-nitrogen-doped carbon nanotubes (VNDCNTs) Crown Copyright (C) 2010 Published by Elsevier B V All rights reserved
