title: Charge transfer and current fluctuations in single layer graphene transistors modified by self-assembled C60 adlayers.
abstract: Flicker noise in a "fullerene + graphene" hybrid transistor is investigated to reveal the electrical coupling between the graphene channel and C60 adsorbates. The charge trapping and detrapping events at the C60 /graphene interface induce current fluctuations in the devices. The evolution of noise characteristics at varying temperatures indicates the different contributions related to Coulomb scattering and charge exchange kinetics.
