| Summary: | Single electron transistor (SET) is a fast device with promising features in nanotechnology. Its operation speed depends on the island material, so a carbon based material such as graphene nanoribbon (GNR) can be a suitable candidate for using in SET island. The GNR band gap which depends on its width, has a direct impact on the coulomb blockade and SET current. In this research, current–voltage characteristic for the SET utilizing GNR in its island is modelled. The comparison study shows the impact of GNR width and length on the SET current. Furthermore SET quantum capacitance is modeled and effect of GNR width and temperature on the quantum capacitance are investigated. |
