Fig. 3: The MD thermal conductivity κ versus the thermal circuit conductivity τ.

Histograms of τ and κ, distinguished by linker type, are shown along the x- and y-axes, respectively. The scaling factors are fitted for ZIFs with identical linkers, yielding good linear correlations when a single coefficient is applied. Pearson coefficients are calculated after excluding two exceptional net topologies, BCT and SOD, which are represented by squares. The gray shading indicates measurement uncertainty, estimated by repeating the current measurement three times with different choices of the unit cell.
