Symmetry-protected coherent transport for diluted vacancies and adatoms in graphene
Symmetry-protected coherent transport for diluted vacancies and adatoms in graphene
We study the effects of a low concentration of adatoms or single vacancies in the linear--response transport properties of otherwise clean graphene. These impurities were treated as localized orbitals, and for each type two cases with distinct coupling symmetries were studied. For adatoms, we considered top- and hollow-site adsorbates (TOP …
