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, 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.
A new technique, developed by a team at Rice University, will allow lithographers to strip back individual, atom-thick, layers of graphene, one at a time, shaping the material into the electronic components it promises to revolutionise.Dr.
Wonder material graphene gets more wonderfully mysterious the closer scientists look. And the latest attempt to understand how the atom-thick sheet of carbon atoms carries current the way it does has left physicists with more questions than they started with.
What if you could have graphene, but instead of it being carbon based, it was silicon based, and therefore already compatible with today's silicon electronics? Welcome silicene, a new wonder material composed of an atom-thick sheet of silicon.
Researchers at Rice University's Department of Mechanical Engineering and Materials Science have successfully created single-atom sheets of an insulator: hexagonal Boron Nitride (h-BN).The breakthrough could help graphene kick silicon back into the 20th century, paving the way for nanoscale field-effect transistors, quantum capacitors or biosensors.
As you probably know, graphene is a one-atom-thick sheet of carbon atoms packed in a dense two-dimensional honeycomb lattice. And it recently became very popular recently as a basis for ultra-fast transistors. Now, according to Science News, U.S. researchers are using graphene to image individual hydrogen atoms via a standard transmission electron microscope (TEM) technology. Until now, heavy atoms, such as carbon, could be detected by electron microscopy. But the physicists from Berkeley, California, have shown it's possible to track the smallest atoms, hydrogen ones.

A team of physicists at the University of California at Riverside (UCR) have found that graphene, which was isolated experimentally only less than three years ago, and which is a one-atom thick sheet of carbon atoms arranged in hexagonal rings, can act as an atomic-scale billiard table. They found that electrons in graphene behave like quantum billiard balls. This research could lead to new kinds of transistors based on quantum physics. In fact, it's possible that graphene can replace silicon as the basic electronic material in a few years. For example, it could be used to develop 'ballistic' transistors.
You may have noticed the odd article about a new form of carbon called graphene. Graphene is certainly an odd substance - it's a layer of carbon atoms in a hexagonal lattice, just one atom thick.
