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?

How to make graphene

Sellotape and sugar rub shoulders with high-temperature furnaces and low-pressure chambers in a rush to produce graphene, which aims to be the 21st century's successor to silicon

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

Peculiar electrons hint at graphene condensate

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.

Looking at single atoms of hydrogen

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. But read more...
