New technology to improve performance of graphene

Establishes foundation for commercialization of graphene-based electronic devices


A research team led by Yonsei Materials Science and Engineering Professor Jongill Hong has developed a new technology that improves the performance of graphene, a remarkable carbon allotrope that is the basic structural element of other allotropes, such as graphite, charcoal, carbon nanotubes, and fullerenes. The research, which has progressed over four years, promises to have important applications in the production of various electronic devices.

The results were published November 10, 2016 in Nature Communications under the title “Hydrogenated monolayer graphene with reversible and tunable wide band gap and its field-effect transistor.” In the words of Professor Hong: “It is anticipated that this research will make a significant contribution to groundbreaking development and commercialization in the field of carbon-based electronics, in particular, transparent electronic devices, which have hitherto been devised only theoretically.” He added: “We will continue to engage in collaborative research with experts in other fields to make pioneering efforts to develop the devices of the future, using promising new materials.”
