The contact conductance of single, double, and triple thermal contacts of single-walled carbon nanotubes (SWCNTs) was investigated using molecular dynamics simulations. Our results showed that the effect of the thermal contact number on the contact conductance was not as strong as previously reported. The percentages of contact conductance of double and triple thermal contacts were about 72% and 67%, respectively, compared to that of a single thermal contact. Moreover, we found that the contact conductance of the double and triple thermal contacts was associated with the SWCNT length and the positional relationship of the thermal contacts.
利用分子动力学模拟研究了单壁碳纳米管（SWCNT）单、双和三重热接触的接触电导。我们的结果表明，热接触数量对接触电导的影响并不像先前报道的那么强烈。与单热接触相比，双热接触和三热接触的接触电导百分比分别约为72%和67%。此外，我们发现双热接触和三热接触的接触电导与SWCNT长度以及热接触的位置关系有关。
