Dissipative Transport in Rough Edge Graphene Nanoribbon Tunnel Transistors
Youngki Yoon, Sayeef Salahuddin
We have studied quantum transport in Graphene Nanoribbon Tunnel Field-Effect Transistors. Unlike other studies on similar structures, we have included dissipative processes induced…
Intrinsic Cut-off Frequency in Scaled Graphene Transistors
Kartik Ganapathi, Youngki Yoon, Sayeef Salahuddin
Using 2-D self-consistent ballistic quantum transport simulations, we investigate the short-channel behavior of graphene field-effect transistors and its impact on the device trans…
Role of Phonon Scattering in Graphene Nanoribbon Transistors: Non-Equilibrium Green's Function Method with Real Space Approach
Youngki Yoon, Dmitri E. Nikonov, Sayeef Salahuddin
Mode space approach has been used so far in NEGF to treat phonon scattering for computational efficiency. Here we perform a more rigorous quantum transport simulation in real space…
Barrier-Free Tunneling in a Carbon Heterojunction Transistor
Youngki Yoon, Sayeef Salahuddin
Recently it has been experimentally shown that a graphene nanoribbon (GNR) can be obtained by unzipping a carbon nanotube (CNT). This makes it possible to fabricate all-carbon hete…
Analysis of InAs Vertical and Lateral Band-to-Band Tunneling Transistors: Leveraging Vertical Tunneling for Improved Performance
Kartik Ganapathi, Youngki Yoon, Sayeef Salahuddin
Using self-consistent quantum transport simulation on realistic devices, we show that InAs band-to-band Tunneling Field Effect Transistors (TFET) with a heavily doped pocket in the…
Non-Linear Temperature Dependence in Graphene Nanoribbon Tunneling Transistors
Youngki Yoon, Sayeef Salahuddin
It is usually assumed that tunneling current is fairly independent of temperature. By performing an atomistic transport simulation, we show, to the contrary, that the subthreshold…
