Heat management with a twist in layered materials

The misalignment of crystal lattices in stacked monolayers of materials has been shown to prevent heat flow between the layers, while retaining flow within them. This finding opens up an inventive way to control heat at the nanoscale.

Any electrical device will eventually break if it overheats. Heat management is therefore a constant challenge in the design of electrical systems — especially if the miniaturization of electronic devices is to continue, because the downsizing of electronic components results in greater amounts of heat being generated per unit volume of a device. Writing in Nature, Kim et al.¹ report findings that might enable heat management to be achieved in dense electronic circuitry by means of highly directional heat dissipation. The trick is to use materials that consist of stacked, atomically thin layers.
