摘要
The flicker noise in a ‘fullerene + graphene’ hybrid transistor is measured by X. H. Qiu and co-workers on page 2420 to reveal the electrical coupling between its graphene channel and C60adsorbates. The charge associated with the trapping and detrapping processes at the C60/graphene interface induces current fluctuations in the device. The temperature-dependent noise characteristics indicate that the two contributions are related to Coulomb scattering and charge-exchange kinetics. This represents a practical template for developing graphene-based biosensors and nanoelectrodes.
