The online magazine Physics World has awarded the research team of Pablo Jarillo-Herrero, a researcher of the MIT, for making a discovery that led to the development of “twistronics”. This promising technique can adjust the electronic properties of graphene by rotation of its adjacent layers. Their first achievement was the creation of magic-angle graphene, which behaves like a high temperature semiconductor.

Whereas boron is a nonmetallic semiconductor in its bulk form, it becomes a metallic conductor in 2D, even at a thickness of only one atomic layer.
