Research paperExperimental CharacterizationComputational DFTTunable interfacial chemisorption with atomic-level precision in a graphene/WSe₂ heterostructureMo-Han Zhang, Fei Gao, Aleksander Bach Lorentzen, Ya-Ning Ren et al.2023·10.5281/zenodo.597181·arXiv:2311.06515AbstractWe demonstrate atomic-level chemical doping in graphene through manipulation of individual selenium atoms extracted from an underlying WSe₂ layer in a graphene/WSe₂ heterostructure. STM measurements and first-principles calculations show that single Se atoms can chemisorb at bridge, A-sublattice, and B-sublattice sites in graphene, producing distinct pseudospin-mediated atomic-scale vortices and localized states. STM tip pulses can manipulate the chemisorption position of individual Se atoms, enabling atomic-scale control of quantum interference in graphene.Read more
