Electron and Hole Photoemission Detection for Band Offset Determination of Tunnel Field-Effect Transistor Heterojunctions
Wei Li, Qin Zhang, R. Bijesh +9
The electrical performance of a tunnel field-effect transistor depends critically on the band offset at their semiconductor heterojunction interface. Historically, it has been diff…
Graphene as Transparent Electrode for Direct Observation of Hole Photoemission from Silicon to Oxide
Rusen Yan, Qin Zhang, Oleg A. Kirillov +10
The outstanding electrical and optical properties of graphene make it an excellent alternative as a transparent electrode. Here we demonstrate the application of graphene as collec…
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…
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…
Zener Tunneling in Semiconducting Nanotube and Graphene Nanoribbon p-n Junctions
Debdeep Jena, Tian Fang, Qin Zhang +1
A theory is developed for interband tunneling in semiconducting carbon nanotube and graphene nanoribbon p-n junction diodes. Characteristic length and energy scales that dictate th…
