Electronic devices based on carbon nanotubes (CNTs) show potential for circuit miniaturization due to their superior electrical characteristics and reduced dimensionality. The CNT field effect transistors (CNFETs) offer breakthrough in miniaturization of various electronic circuits. Investigation of ballistic transport governing the operation of CNFETs is essential for understanding the device's functional behavior. This investigation is focused on a study of current–voltage characteristics of device behavior in hard saturation region. The investigation utilizes a set of current–voltage characteristics obtained on typical devices. This work is an extension of our earlier work describing application of our approach to Si -MOSFET behavior in the saturation region.

Abstract Graphene devices for radio frequency (RF) applications are of great interest due to their excellent carrier mobility and saturation velocity. However, the insufficient current saturation in graphene field effect transistors (FETs) is a barrier preventing enhancements of the maximum oscillation frequency and voltage gain, both of which should be improved for RF transistors. Achieving a high output resistance is therefore a crucial step for graphene to be utilized in RF applications. In the present study, we report high output resistances and voltage gains in graphene-on-silicon (GoS) FETs. This is achieved by utilizing bare silicon as a supporting substrate without an insulating layer under the graphene. The GoSFETs exhibit a maximum output resistance of 2.5 MΩ∙μm, maximum intrinsic voltage gain of 28 dB, and maximum voltage gain of 9 dB. This method opens a new route to overcome the limitations of conventional graphene-on-insulator (GoI) FETs and subsequently brings graphene electronics closer to practical usage.
