The study of film´s local vacancy defect effects on the thermal conductivities of argon thin films

It is well known that the vacancy defect in solid will reduce the thermal conduction and the thermal conductivity of thin film is lower than bulk counterpart. In this paper one novel film structure was constructed to study the local vacancy defect effects on the thermal conductivities of argon thin films by molecular simulation. Both the theoretical and MD simulation results illustrate that although both the defect and thickness of thin film deduce the thermal conductivity, their physical mechanisms are different.
