“…With complete characterization of the physical system being studied, the MD simulation method allows for a systematic study of the dependence of CNT-CNT conductance on parameters that may be modified to optimize the thermal properties of CNT-based materials. The simulations have provided important insights into the mechanisms responsible for the inter-tube heat transfer between parallel CNTs [53][54][55][56] or CNTs crossing each other at an angle [51,58,[67][68][69]. While the variation of the values of the conductance per unit area of the inter-tube contacts by more than two orders of magnitude [56] suggests a strong and complex dependence of the inter-tube conductance on the geometry and density of the contacts, the design of a general heat transfer model that would account for this dependence is hampered by the differences in computational methods, interatomic potentials, definitions of the contact area, length and type of the CNTs used in the simulations, etc.…”
