In materials science and quantum physics, flat bands and correlated behaviors within the "magic angle" twisted bilayer graphene (tBLG) has sparked significant interest, although many of its properties face intense debate. ...
(Phys.org)—Electrons can move through graphene with almost no resistance, a property that gives graphene great potential for replacing silicon in next-generation, highly efficient electronic devices. But currently it's ...
A Princeton University-led team of scientists has imaged the precise microscopic underpinnings responsible for many quantum phases observed in a material known as magic-angle twisted bilayer graphene (MATBG). This remarkable ...
