Using first-principles modeling, we investigate how phonon transport evolves in layered/van der Waals materials when going from 3D to 2D, or vice versa, by gradually pulling apart the atomic layers in graphite to form graphene. Focus is placed on identifying the features impacting thermal conductivity that are likely shared with other layered materials. The thermal conductivity $\kappa$ of graphite is found to be lower than that of graphene mainly due to changes in the phonon dispersion driven… 


Dimensional crossover of thermal transport in few-layer graphene.
The observed evolution from two dimensions to bulk is explained by the cross-plane coupling of the low-energy phonons and changes in the phonon Umklapp scattering, shedding light on heat conduction in low-dimensional materials and may open up FLG applications in thermal management of nanoelectronics.
