  We proposed a new way, adding intertube atoms, to enhance interfacial thermal
conductance (ITC) between SiC-carbon nanotube (CNT) array structure.
Non-equilibrium molecular dynamics method was used to study the ITC. The
results show that the intertube atoms can significantly enhance the ITC. The
dependence of ITC on both the temperature and the number of intertube atoms are
shown. The mechanism is analyzed by calculating probability distributions of
atomic forces and vibrational density of states. Our study may provide some
guidance on enhancing the ITC of CNT-based composites.
