Molecular dynamics calculations of the cross-plane thermal conductivity of GaAs/AlAs superlattices with rough interfaces.
Résumé
A molecular dynamics investigation of the thermal conductivity of superlattices is presented. The interface roughness is modeled using rectangular islands, as in the case of realistic interfaces. Our results confirm the findings of previous studies. When interfaces with heights of two monolayers are considered, the thermal conductivity is higher than that in the case of perfect interfaces.
