Thermal conductivity versus the side length of simulation cell.
The mass ratio of the 3D isotopic phononic crystal is 2 and the period length is 2 units. The error bars are calculated from 16 simulations with different initial conditions. All values are calculated at 1000 K which is larger than the Debye temperature, TD, of Si (~658 K).
