Abstract
The effect of stacking configuration on the phonon-based thermal conductivity of graphite is investigated using equilibrium molecular dynamics. Hexagonal (AAA), Bernal (ABA), and Rhombohedral (ABC) stacking forms are considered in a 5×5nm domain. The intralayer thermal conductivity values are predicted to be 450–800W/mK for both zigzag and armchair directions for different configurations, which are in agreement with previous results for graphite and few-layer graphene. The interlayer thermal conductivity values are calculated in the range of 9–55W/mK. The intralayer thermal conductivity in the armchair direction appears to increase with increasing vertical alignment of carbon atoms in adjacent layers.
