A layered form of graphene shows a rare semimetal state with balanced electrons and holes that becomes a topological insulator when exposed to moderate magnetic fields. (Nanowerk Spotlight) Semimetals ...

Engineers have discovered an unexpected link between two very different realms of physics: the behavior of electrons in ...

The nano-IR imaging set-up for studying the moiré graphene lattice. (Courtesy: G Ni) Researchers at the University of California at San Diego (UCSD) are the first to have used infrared nano-imaging to ...

The electronic and magnetic properties of two-dimensional materials both have strong potential for technological applications. Researchers have long assumed that they are distinct phenomena, but ...

Ordinary pencil lead holds extraordinary properties when shaved down to layers as thin as an atom. A single, atom-thin sheet of graphite, known as graphene, is just a tiny fraction of the width of a ...

The study was conducted under the project New approaches to deciphering the structure and chemical properties of graphene oxide, supported by a grant from the Russian Science Foundation. Graphene ...

Two dimensional materials have drawn intense interest because their electronic and magnetic properties could power future technologies. Scientists ...
