The band structure of a representative three-dimensional ... The energy bands of two-dimensional graphene (right) are smooth-sided cones, which meet at the Dirac point. Disclaimer: AAAS and ...

In 2018, Jarillo-Herrero discovered that when two graphene sheets are stacked on top of each other, at a precise, “magic” angle, the twisted structure — known as magic-angle twisted bilayer graphene, ...

For example, a second magic angle has been reported at around 1.3°, which is close to the primary magic angle. At this angle, the electronic structure of the twisted bilayer graphene exhibits similar ...

Researchers from The University of Manchester and the University of Warwick finally solved the long-standing puzzle of why graphene is so much more permeable to protons than expected by theory. A ...
