A new way to make sheets of graphene
Graphene's promise as a material for new kinds of electronic devices, among other uses, has led researchers around the world to study the material in search of new applications. But one of the biggest limitations ...
Researchers find a way to integrate two two-dimensional materials into a single electronic device
Hybrid nanotube-graphene material promises to simplify manufacturing
(Phys.org) —Carbon nanotubes are reinforcing bars that make two-dimensional graphene much easier to handle in a new hybrid material grown by researchers at Rice University.
Argonne scientists are first to grow graphene on silver
(Phys.org) —Silver, meet graphene. Super strong, super light, near totally transparent and one of the best conductors of electricity ever discovered, graphene is a one-atom-thick sheet of carbon atoms that ...
'Diamane': Diamond film possible without the pressure
(Phys.org) —Perfect sheets of diamond a few atoms thick appear to be possible even without the big squeeze that makes natural gems.
Researchers invent 'sideways' approach to 2-D hybrid
(Phys.org) —Researchers at the Department of Energy's Oak Ridge National Laboratory and the University of Tennessee, Knoxville have pioneered a new technique for forming a two-dimensional, single-atom sheet ...
'White graphene' halts rust in high temps
(Phys.org) —Atomically thin sheets of hexagonal boron nitride (h-BN) have the handy benefit of protecting what's underneath from oxidizing even at very high temperatures, Rice University researchers have ...
Graphene 'onion rings' have delicious potential
Concentric hexagons of graphene grown in a furnace at Rice University represent the first time anyone has synthesized graphene nanoribbons on metal from the bottom up—atom by atom.
2-D electronics take a step forward: Team makes semiconducting films for atom-thick circuits
Scientists at Rice University and Oak Ridge National Laboratory (ORNL) have advanced on the goal of two-dimensional electronics with a method to control the growth of uniform atomic layers of molybdenum disulfide ...
Even with defects, graphene is strongest material in the world
In a new study, published in Science May 31, 2013, Columbia Engineering researchers demonstrate that graphene, even if stitched together from many small crystalline grains, is almost as strong as graphene in its ...
Even graphene has weak spots: Theorists find junctions in polycrystalline graphene sap its strength
(Phys.org) —Graphene, the single-atom-thick form of carbon, has become famous for its extraordinary strength. But less-than-perfect sheets of the material show unexpected weakness, according to researchers ...
New study gives insight into graphene grain boundaries
(Phys.org)—Using graphene – either as an alternative to, or most likely as a complementary material with – silicon, offers the promise of much faster future electronics, along with several other advantages ...
Self-assembled monolayers create p-n junctions in graphene films
Researchers are creating graphene p-n junctions by transferring films of the electronic material to substrates that have been patterned by compounds that are either strong electron donors or electron acceptors.
Controlling heat flow through a nanostructure
MIT researchers find that heat moving in materials called superlattices behaves like waves; finding could enable better thermoelectrics.
