How did graphne become involved in trqnsistors research, and were there any problems along the way? Previous left arrow key Next right arrow key Close Move. Would you summarize the significance of your paper in layman’s terms? Graphene holds great potential for future electronics, and its destiny is largely linked to various materials issues that need to be resolved, including the synthesis of large-scale, high-quality graphene sheets and the improvement of the device fabrication process.

The major challenges of this work included the design of the graphene transistor and the deposition of a high-quality oxide film as the gate insulator. Message Subject Your Name has forwarded a page to you from Science. This paper is likely well-cited because it presents one of the first experimental demonstrations of gigahertz graphene transistors with the highest frequency reported thus far, and establishes the hraphene behavior of device performance with respect to the device dimension.

GHz Transistors from Wafer-Scale Epitaxial Graphene | Science

In this paper, we presented an approach to fabricate top-gated graphene transistors using exfoliated graphene extracted from a graphite crystal, and demonstrated the operation of the graphene transistors at a frequency as high waer-scale 26 gigahertz, or 26 billion cycles per second.

The author has also sent along images of his eitaxial. Graphene is a material that has generated enormous research interest and activity in the past few years because of its unique electrical properties and its potential for use in future electronics.

Why do you think your paper is highly cited? Yu-Ming Lin talks with ScienceWatch. I was already exploring electrical transport properties of graphene and its nano-ribbons, fgom became involved with the fabrication and characterization of graphene transistors when the CERA program was launched in May, Does it describe a new discovery, methodology, or synthesis of knowledge? The work benefited greatly from the insightful discussions and guidance of Dr.
