I calculated of the thermal conductivity along a copper film with various thicknesses: d = 400, 100 and 50 nm at 300 K. This plot illustrates the size dependence of the effective thermal conductivity, using the size-effect effective conductivity based on Kn number and. The obtained plot is very similar to Figure 5.17 of the book “Nano/Microscale Heat Transfer”, Zhuomin M. Zhang, McGraw-Hill, page 175.
