  • Charged adsorbates on graphene

    "Crystals are like people — it’s the defects in them that make them interesting” (F. C. Franks). 2D materials, such as graphene, are no exception and adsorbates on graphene are known to affect many of its remarkable intrinsic properties. Furthermore, these adsorbed impurities can be electrically charged (so called “Coulomb” impurities) and their electronic and optical properties are not only interesting from a purely scientific perspective, but may have important implications for the development of future optoelectronic device technologies based on 2D materials.
