摘要：
The cross-plane thermal conductivity of WSe2 is investigated using reverse nonequilibrium molecular dynamics (RNEMD) and a recently developed Stillinger-Weber potential. It is found that the cross-plane thermal conductivity of WSe2 is strongly size dependent and saturates around 80 layers. Moreover, it is shown that even at 1000 K, ordered crystalline WSe2 does not reach the phonon glass-like limit in the cross-plane direction. © 2017 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim
