…would allow for fabrication of extremely small and low-power circuits. The proposed approach for graphene circuits presents a conceptual change in graphene research and indicates an alternative route for graphene’s…
…at Chicago and Korea University have developed a supersonic spray that delivers a high-quality graphene layer. A simple, inexpensive spray method that deposits a graphene film can heal manufacturing defects…
A newly published study from Rice University shows that graphene is 10 times better than steel at absorbing the energy of a penetrating projectile. Graphene’s great strength appears to be…
Schematic image showing graphene-TMD heterostructure. The TMD causes giant anisotropy in spin transport in graphene. Dámaso Torres, ICN2 The strong collaborative ethos of the Graphene Flagship is accelerating developments in…
…how much energy it takes to bend multilayer graphene – a question that has eluded scientists since graphene was first isolated. The findings are reported in the journal Nature Materials…
…transistor (FET). To address this issue, researchers have tried cutting the graphene sheet into small pieces of graphene nanoribbon, successfully opening up a bandgap. However, the current of graphene nanoribbons…
Snowflakes etched in graphene at Skoltech. The light areas are graphene, and the dark ones are oxidized copper. The snowflake pattern emerged as the surrounding graphene was etched away by…
…time resolution of photocurrent measurements in graphene into the picosecond range. While conducting their research, they were able to monitor precisely how the photocurrent in the graphene is generated and…
…weakness. A new study reveals that even graphene has weak spots, finding that junctions in polycrystalline graphene will reduce its strength. Graphene, the single-atom-thick form of carbon, has become famous…
Copper substrate is shown in the process of being coated with graphene. At left, the process begins by treating the copper surface, and, at right, the graphene layer is beginning…
