Metal–Insulator–Graphene diodes enable terahertz rectennas on flexible substrates

Researchers from AMO GmbH, RWTH Aachen University, Chalmers University and the University of Wuppertal have recently developed a novel type of graphene-based flexible energy harvester, which reportedly shows good prospects for powering wearable and conformal...

New method creates sub-10-nm GNRs from squashed carbon nanotubes

Researchers at Shanghai Jiao Tong University, Stanford University, and other US and China institutes have designed a strategy for creating graphene nanoribbons (GNRs) with smooth edges that are below 10 nm in width. This new method is based on the use of squashed...

Researchers take a closer look at a mysterious graphene oxide phenomenon

A team of researchers at UNSW has observed a unique phenomenon in graphene oxide (GO). The oxygen atoms in GO are normally attached in a rather chaotic way. At elevated temperatures, however, the oxygen atoms form more organized structures – by themselves. This...

Researchers discover a correlated electron-hole state in double-bilayer graphene

A team of researchers, led by Klaus Ensslin and Thomas Ihn at the Laboratory for Solid State Physics at ETH Zurich, together with colleagues at the University of Texas in Austin (USA), has observed a novel state in twisted bi-layer graphene. In that state, negatively...

Researchers develop simple method to achieve fine control over the integration of foreign atoms into graphene

Researchers from South Korea invented a simple way to achieve fine control over the integration of foreign atoms with graphene, developing composite graphene-based heterostructures that can be used to store energy at low cost and fabricate ultrathin, wearable...
