Fig. 2: An example of a 2D crystal network and its corresponding electrical circuit.

a Nodes represent atoms at the intersections of heat conduction paths, and edges denote the connecting atoms and chemical bonds. In ZIFs, each node corresponds to a Zn atom, and each edge to a Zn-linker-Zn “heat conduction unit” (inset). b Each resistor, with a resistance of 1 Ω, represents a heat conduction unit. A voltage of 1 V is applied to the circuit, and the current flowing through it is computed.
