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.

Adsorption Of Co2

In this paper, I present first-principle calculations which are performed by using combination of DFT and NEGF methods to investigate the adsorption of CO2 and NH3 molecules on straight and U-shaped GNRs junctions. The density of state, molecular orbital, adsorption energy, transmission spectrum, and current-voltage characteristics were analyzed. It is found show that the adsorption of CO2 and NH3 on straight GNRs at the dangling bond edges exhibit chemical interaction behavior with high adsorption energy. Besides, for U-shaped ZGRNs without adsorption, the states around Fermi level are quasi-bound states localized at the zigzag edges. The electrons at these localized states are almost confined and do not contribute on conductance. However, for U-shaped GRNs with CO2 and NH3 adsorbed on dangling bond armchair edges, these states become delocalized on whole of the U-shaped junction. The current-voltage characteristics show that the sensitivity and selectivity of the U-shaped GNRs gas sensors are significantly improved in comparison with the pristine GNRs ones.
