Fig. 4. Illustration of superlattice reduction in thermal conductivity, from Rawat et al. 44 Cross-plane thermal conductivity of 300 nm thick ZrN/ScN (dots) and Zr0.64W0.36N/ScN (squares) multilayers. Superimposed on the plot are horizontal lines corresponding to the experimentally determined lattice component of thermal conductivity, i.e., the alloy limit of different alloys of ZrN, ScN, and W2N.
