(Phys.org)—A team of researchers with members from institutions in the U.S., Korea and China has developed a new way to make bilayer graphene that is higher in quality than that produced through any other known process. ...
(Phys.org)—Electrons can move through graphene with almost no resistance, a property that gives graphene great potential for replacing silicon in next-generation, highly efficient electronic devices. But currently it's ...
To the list of potential applications of graphene – a two-dimensional semiconductor of pure carbon that is stronger and much faster than silicon – we can now add valleytronics, the coding of data in the wavelike motion ...
