New graphene nanoribbons could enable smaller electronic devices

A new collaborative study has reported a 17-carbon wide graphene nanoribbon and found that it has the tiniest bandgap observed so far among familiar graphene nanoribbons prepared through a bottom-up approach.(a) Bottom-up synthesis scheme of 17-AGNR on Au(111), (b)...

Laser technique that opens a bandgap in graphene could allow for next-gen graphene electronics

Researchers from Purdue University, the University of Michigan and the Huazhong University of Science and Technology have used a technique called "laser shock imprinting" to permanently stress graphene into having a band gap, which could mean it would be...

Researchers bind hydrogen to graphene in a super-fast reaction that also opens up a bandgap

Researchers from Göttingen and Pasadena (USA) have produced an "atomic scale movie" showing how hydrogen atoms chemically bind to graphene in one of the fastest reactions ever studied. The team found that by adhering hydrogen atoms to graphene, a...
