A a new cooling mechanism for electronic components made of graphene deposited on boron nitride

Tue, 01/09/2018 - 19:40
Optics and mesoscopic physics teams have discovered a new cooling mechanism concerning electronic components made of graphene deposited on boron nitride. The efficiency of this mechanism allowed them to reach electric intensities at the intrinsic limit of the laws of conduction. This new mechanism, which exploits the two-dimensional nature of the materials opens a 'thermal bridge' between the graphene sheet and the substrate. Researchers have demonstrated the effectiveness of this mechanism by imposing in graphene levels of electrical current still unexplored, up to the intrinsic limit of the material and without any degradation of the device.
