Nonequilibrium molecular dynamics simulation of the in-plane thermal conductivity of superlattices with rough interfaces
K Termentzidis and P Chantrenne and P Keblinski, PHYSICAL REVIEW B, 79, 214307 (2009).
We report nonequilibrium molecular dynamics study of heat transfer in binary Lennard-Jones superlattices. The influence of the characteristic height of the interface roughness and the superlattice period on the in- plane thermal conductivity is reported. We observe that in-plane thermal conductivity first decreases with an increase in the characteristic height of the roughness. For perfectly periodic roughness, it seems that the thermal conductivity exhibit a minimum value when the characteristic height of the roughness becomes comparable with the superlattice period.
