Fig. 3

Comparison of the accumulative κ with respect to phonon mean free path for (a) GaN with anisotropy and (b) BAs at different temperatures, respectively. The insets are electron localization function (ELF). The converging (c) normalized heat current autocorrelation function (HCACF) and the (d) corresponding κ at 300 K for BAs as a function of simulation time, where the shaded area indicates the statistical uncertainty on the mean value from 14 independent simulations.
