Graphene stress produces gigantic pseudo-magnetic fields

Researchers have reported the creation of pseudo-magnetic fields far stronger than the strongest magnetic fields ever sustained in a laboratory – just by putting the right kind of strain onto a patch of graphene (a sheet made from a single layer of carbon atoms). The finding, reported in Science, adds to graphene’s growing list of […]

Graphene’s “Muffin-Tin” Nanodots Explained




Researchers believe they now understand how graphene – a featureless, one-atom-thick sheet of carbon atoms – lying on an equally featureless iridium surface, self-created a kind of “muffin tin” that formed identically sized and spaced muffins out of applied iridium atoms. “At the outset,” writes Sandia researcher Peter Feibelman, who devised the explanatory simulation published […]

Smallest Transistor Created With Graphene




University of Manchester researchers have used the world’s thinnest material, graphene, to create the world’s smallest transistor, one atom thick and ten atoms wide. Reporting their work in Science, Dr Kostya Novoselov and Professor Andre Geim show that graphene can be carved into tiny electronic circuits with individual transistors having a size not much larger […]

Single-Atom-Thick Materials Almost Ready For Prime Time




British and Russian scientists led by Professor Andre Geim at the University of Manchester believe they have uncovered a whole family of previously unknown materials that are only one atom thick. The new research, published in the Proceedings of the National Academy of Sciences, follows on from the team’s earlier work on the material graphene. […]

Nano-Fabric Reveals Unique Properties




Researchers from the UK and Russia have unveiled – in the journal Science – the world’s first single-atom-thick fabric. The research team, led by Andre Geim at The University of Manchester, has succeeded in extracting individual planes of carbon atoms from graphite crystals, which has resulted in the production of the thinnest possible fabric – […]
