Samsung touts process to commercialize graphene

Samsung's new process to synthesize graphene---a form of carbon more durable than steel and flexible for use in displays and wearables---could apply broadly to its product lineup over time.

Graphene research: shear forces to sheer displays

Lab tests have confirmed theoretical predictions about the shear and strain that single sheets of graphene can withstand, bringing industrial and commercial applications of the material a step closer.The two-dimensional, hexagonal lattice of carbon has piqued the interest of display and solar cell manufacturers because of its transparency and high conductivity.

Researchers shed light on photoelectricity in graphene

Graphene has revealed yet more interesting characteristics, as researchers in the US investigate the way the two-dimensional form of carbon reacts to light. Regular readers will not be surprised to learn that it differs a little from a typical semi-conductor.

Osborne puts £50m into UK graphene research

Chancellor George Osborne has promised £50 million for research into graphene, the carbon-based material tipped as a breakthrough in material science, nanotechnology and electronics.Graphene was discovered in 2004 by Dr (now Professor) Kostya Novoselov and Professor Andre Geim from the University of Manchester in work that won them the 2010 Nobel Prize for physics.

For orderly graphene sheets, just add Hydrogen

Researchers have known for some time that the quality of graphene produced by vapour deposition depends on a number of factors: the carbon source and the substrate material being major players.However, scientists at the US Department of Energy’s National Laboratory in Oak Ridge have found that hydrogen plays a much more active role in the formation of the material than previously thought.

How does graphene work?

Graphene gets its unique properties from the geometry of its carbon atoms. But how does something so simple produce such profoundly different physics?

What is graphene?

Carbon is valuable as diamond and in oil, but a new form of the pure element may be even more important in our future. ZDNet UK presents the first in a series of features on graphene

Graphene's good vibrations for supersensitive detectors

Graphene and its curlier cousin, the carbon nanotube, could revolutionise yet another field, as researchers find that when built into teeny tiny resonators, they have been shown to exhibit non-linear damping.Oh-ho, you say, this could lead to supersensitive devices to detect force or mass.

Graphene-based modulator promises ultra-fast comms

Researchers at the University of California, Berkeley, have created a graphene-based optical modulator that they think could lead to digital communications up to 10 times faster than is possible with currently-deployed technology.Graphene is a one-atom thick layer of crystallised carbon that many hope will overcome the limitations of silicon and lead to viable quantum computing.

Graphene lines up vacancies for a magnetic moment

With the right engineering, graphene could be made to behave like a ferromagnet, according to new research which has uncovered a so-called tunable Kondo Effect in holey sheet of the 2-dimensional carbon lattice.Physics Professor Michael S.

IBM clocks graphene transistor at 155GHz

IBM has demonstrated a new super whizzy graphene transistor, clocking in at 155GHz, up from the 100GHz it benched last year.The breakthrough was made possible because the transistor was set on a substrate of "diamond-like carbon", itself layered on a commercial silicon wafer.

Graphene adds self-cooling to list of super powers

Graphene, twice threatened by silicon's atom-thick offspring silicene, the pretender to its carbon throne, has hit back with yet another amazing characteristic: transistors made from the atom-tick carbon mesh will cool themselves.Heat is the bane of the electronics industry’s life.

Building blocks for perfect carbon nano ribbons

German researchers have developed a new technique for building carbon nano ribbons: instead of slicing up larger sheets of graphene, they are building them, piece by piece, from the bottom up.This has the major advantage of allowing the scientists control over the dimensions of the ribbons.
