Researchers from Brown and Columbia Universities in the U.S have demonstrated that unknown states of matter arise from stacking two-dimensional layers of graphene together. These new states have been named the fractional quantum Hall effect (FQHE), and are created through the complex interactions of electrons within and across graphene layers.

“In terms of materials engineering, this work shows that these layered systems could be viable in creating new types of electronic devices that take advantage of these new quantum Hall states,” said Jia Li, assistant professor at Brown. Li added: “The findings show that stacking 2-D materials together in close proximity generates entirely new physics.”

Further demonstrating the potential importance of this research, the team pointed out that these new quantum Hall states “may be useful in making fault-tolerant quantum computer.” [Read the full article here]

 

About the National Graphene Association (NGA)

The National Graphene Association is the main organization and body in the U.S. advocating and promoting the commercialization of graphene. NGA is focused on addressing critical issues such as policy and standards development that will result in effective integration of graphene and graphene-based materials globally. NGA brings together current and future graphene stakeholders — entrepreneurs, companies, researchers, developers and suppliers, investors, venture capitalists, and government agencies — to drive innovation, and to promote and facilitate the commercialization of graphene products and technologies.
