New Way to Control Heat in 2D Materials


Two-dimensional (2D) materials such as those made from transition metal dichalcogenides (TMDs) are  layered one on top of another to create devices that could potentially be used for electronics. In fact, how these materials are layered determines to a large extent the electronic properties of the final device.

One property that engineers have kept in mind when plotting the layering of TMDs and other 2D materials is how they dissipate heat. Researchers at North Carolina State University, the University of Illinois at Urbana-Champaign (UI) and the Toyota Research Institute of North America (TRINA) have discovered an almost counterintuitive phenomenon in the layering of 2D materials that should help them to dissipate heat when they are fabricated into electronic devices.
