The single electron transistor is a nanoscale switching device with a simple equivalent circuit. As the quantum dot island in SETs, carbon allotropes such as fullerene, carbon nanotubes, and graphene nanoscrolls can be used as the quantum dot island. The results reveal that the GNS-CNT SET has a lower Coulomb blockade range and a higher current than the GNS-C60 SET. According to their charge stability charts, the GNS-CNT SET has smaller Coulomb diamond areas, zero-current regions, and zero-conductance regions than the GNS-C60 SET.
