3D "White graphene" could cool electronics

Researchers at Rice University developed a theoretical model that shows how a 3D lattice of boron nitride (also known as "white graphene" as it shares many similar qualities with it, but is not made of carbon atoms) could be deployed as a tunable material to control heat flow in electronic devices. Cooling measures that prevent overheating in electronics are important for developing and sustaining advanced electronic components.

Its 3D structure allows the speculated boron nitride system to conduct heat in any direction as opposed to most circuits, in which heat moves in one direction. The multiple heat directing properties of boron nitride provide excellent opportunities to ‘cool’ down electronic devices. This can be controlled further by building pillars of boron nitride of differing shapes and thickness.

Based on the theoretical findings, research will begin on developing practical models to test out the properties as part of the development of next-generation electronics.
