WebApr 7, 2024 · Graphene, a Dirac semimetal, exhibits the simplest lattice configuration and band structure in the world of two-dimensional materials. Due to its remarkable brevity and tunability, graphene becomes an ideal platform for studying the fundamental physics arising from the linear dispersion around the Dirac point, as well as for exploring symmetry … WebSep 27, 2024 · The marked effect of twistronics is exemplified by the recent groundbreaking works that demonstrated the emergence of extremely flat bands when two monolayer graphene layers are stacked at a “magic” twist angle, θ = 1.1 ± 0.1° (8, 9). In these twisted bilayer graphene (tBLG) devices at the magic angle, an insulating phase is observed at ...
