Graphene is a one-atom-thick sheet of carbon atoms in a hexagonal arrangement. It has been extremely difficult to create graphene-based devices that reliably operate at room temperature and pressure, until…
…arise, creating an almost imperceptible twist in the final bilayer graphene that prevents the graphene from becoming fully insulating even under a very strong electric field. Researchers with the U.S….
…by Emily Hacopian/Lou Group Rice University researchers have found that fracture-resistant “rebar graphene” is more than twice as tough as pristine graphene. Graphene is a one-atom-thick sheet of carbon. On…
…for producing graphene at the industrial scale. Graphene may be among the most exciting scientific discoveries of the last century. While it is strikingly familiar to us — graphene is…
MIT physicists have found a new way to switch superconductivity on and off in magic-angle graphene. This figure shows a device with two graphene layers in the middle (in dark…
Graphene exhibits different behaviors depending on the material it’s wrapped around. A newly published study from MIT researchers details how the behavior of graphene can be drastically different when sheets…
…scientists is a graphene ribbon, which is a very narrow strip of graphene that confines the material’s electrons, giving it new properties. Graphene doesn’t normally have a bandgap — a…
…discovered how to change the crystal structure of graphene, more commonly known as pencil lead, with an electric field, an important step toward the possible use of graphene in microprocessors…
…layers of atomically thin graphene. When sandwiched between 2D layers of boron nitride, the graphene layers — described as trilayer graphene in the study — form a repeating pattern called…
…said senior author James Hone, Wang Fong-Jen Professor of Mechanical Engineering at Columbia Engineering. “This is a milestone towards large-scale production of graphene.” Historical Methods of Graphene Production Graphene has…
…critical to graphene’s extraordinary properties. Perhaps no other material is generating as much excitement in the electronics world as graphene, sheets of pure carbon just one atom thick through which…
…new manufacturing process for graphene is based on using an intermediate carrier layer of material after the graphene is laid down through a vapor deposition process. The carrier allows the…
…group has been exploring electronic behavior in graphene, which by itself has exhibited exceptional properties. Most recently, Ju’s group has looked into pentalayer graphene — a structure of five graphene…
…was stretched back, the adhered graphene will pull on the crumpled graphene to unfold it. “In this way, the crumpling and unfolding of large-area atomic-thick graphene can be controlled by…
…in pristine graphene, they also present completely new opportunities for directly exploring and understanding electronic behavior in graphene.” Reference: “Observing Atomic Collapse Resonances in Artificial Nuclei on Graphene” by Yang…
…Institute have demonstrated that graphene meets an important condition for use in novel lasers for terahertz pulses with long wavelengths, dispelling previous doubts. Graphene is considered the jack-of-all-trades of materials…
