Distribution of the Berry curvature in graphene doped with W atoms
Shown is the distribution of the Berry curvature of graphene doped with tungsten adatoms in a 4x4 superlattice geometry in the reciprocal space. The emergence of the non-zero Berry curvature, which plays a role of a magnetic field in reciprocal space, leads to the occurrence of the quantum anomalous Hall effect in the system - phenomenon, which is being currently intensively researched and sought for experimentally in the field of Chern and topological insulators.
