Engineering quantum anomalous/valley Hall states in graphene via metal-atom adsorption: An<i>ab-initio</i>study
We systematically investigate the magnetic and electronic properties of graphene adsorbed with diluted 3$d$ transition and noble-metal atoms using first-principles calculation methods. We find that most transition-metal atoms (i.e., Sc, Ti, V, Mn, Fe) favor the hollow adsorption site, and the interaction between magnetic adatoms and the $\ensuremath{\pi}$ orbital of …
