Prof. Adam explained, "By situating graphene between the boron nitride substrates and adjusting the alignment to specific twist angles, we can induce topological flat bands in graphene's energy ...
At this angle, the electronic structure of the twisted bilayer graphene exhibits similar flat electronic bands and correlated electronic states ... the existence of additional magic angles at higher ...
"In twisted bilayer graphene, at certain 'magic' twist angles, these bands evolve into flat bands because the interlayer coupling between the layers is adjusted to the right spot," says Chiu.
formed by stacking two graphene layers with a slight twist angle. At specific magic angles, TBG exhibits exotic properties such as superconductivity, correlated insulating states, and flat electronic ...
