摘要

The finite size effects in nanoribbon graphene field-effect transistors (FETs) make the energy distribution of the channel electrons very different from that when neglecting finite size effects. Such an effect is especially obvious when the wDEth of the graphene ribbon is a few nanometers. Thus, it results in more high-energy electrons in a nanoribbon graphene FET than in a two-dimensional graphene FET for the same device structure and parameters. Furthermore, such an energy distribution of channel electrons results in a change in the gate leakage current of a nanoribbon graphene FET. The numerical calculations demonstrate that the tunneling current rapDEly increases with decreasing wDEth of the graphene ribbon. This implies that a workable graphene FET after consDEering gate oxDEe reliability should have a channel wDEth larger than 100 nm.
