Thermal conductivity of SWCNTs remains unaffected by the presence of single-atom vacancy defects.

Thermal conductivity of SWCNTs remains unaffected by the presence of single-atom vacancy defects. Correct Answer True

CNTs possess single – atom vacancies that excessively reduce their thermal conductivity. This happens as the defects locally disrupt the hexagonal network of CNTs. In SWCNTs these defects are energetically metastable, a rebonding of two dangling – bond atoms take place and only one dangling – bond atom is left as a result of thermal treatments.
