Researchers measure single atoms in a graphene ‘petri-dish’

Researchers have shown that graphene and boron nitride can be combined to create a perfect nano petri-dish. Liquid samples inside the dish can be imaged with single atom sensitivity and it is also possible to measure their elemental composition at the nanometre length scale.

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

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.
