Influence of Metal-Graphene Contact on the Operation and Scalability of Graphene Field-Effect-Transistors
Pei Zhao, Qin Zhang, Debdeep Jena +1
We explore the effects of metal contacts on the operation and scalability of 2D Graphene Field-Effect-Transistors (GFETs) using detailed numerical device simulations based on the n…
Ultimate RF Performance Potential of Carbon Electronics
Siyuranga O. Koswatta, Alberto Valdes-Garcia, Mathias B. Steiner +2
Carbon electronics based on carbon nanotube array field-effect transistors (AFETs) and 2-dimensional graphene field-effect transistors (GFETs) have recently attracted significant a…
On the possibility of obtaining MOSFET-like performance and sub-60 mV/decade swing in 1D broken-gap tunnel transistors
Siyuranga O. Koswatta, Steven J. Koester, Wilfried Haensch
Tunneling field-effect transistors (TFETs) have gained a great deal of recent interest due to their potential to reduce power dissipation in integrated circuits. One major challeng…
Scalability of Atomic-Thin-Body (ATB) Transistors Based on Graphene Nanoribbons
Qin Zhang, Yeqing Lu, Huili Grace Xing +2
A general solution for the electrostatic potential in an atomic-thin-body (ATB) field-effect transistor geometry is presented. The effective electrostatic scaling length, λeff, is…
p-i-n Tunnel FETs vs. n-i-n MOSFETs: Performance Comparison from Devices to Circuits
Yunfei Gao, Siyuranga O. Koswatta, Dmitri E. Nikonov +1
The band-to-band tunneling transistors have some performance advantages over the conventional MOSFETs due to the <60mV/dec sub-threshold slope. In this paper, carbon nanotubes are…
Computational study of exciton generation in suspended carbon nanotube transistors
Siyuranga O. Koswatta, Vasili Perebeinos, Mark S. Lundstrom +1
Optical emission from carbon nanotube transistors (CNTFETs) has recently attracted significant attention due to its potential applications. In this paper, we use a self-consistent…
