Engineers at ETH Zurich have now managed to tweak the overachieving material so that some parts of a flake can be an electrical insulator while ... Known as “magic angle twisted bilayer graphene ...

By twisting the top layer to a “magic angle” of 1.1 degrees off-kilter, the double-layer structure could suddenly shift between being an electrical insulator and a superconductor. In two new ...

Physicists at MIT and Harvard University claim they are able to tune graphene to behave as an insulator and a superconductor ... not on top of each other but in a precise angle of 1.1°. The physicists ...
