Recent Developments in Nanotechnology using Graphene

Light-speed Nanotechnology: Controlling The Nature Of Graphene: Researchers have discovered a new method for controlling the nature of graphene, bringing chip manufacturers one step closer to realizing the mass production of graphene-based nanoelectronics. The chemistry of the surface on which graphene is deposited plays a key role in shaping the material's conductive properties: results show that when deposited on a surface treated with oxygen, graphene exhibits semiconductor properties. When deposited on material treated with hydrogen, graphene exhibits metallic properties.[1]
Speed Bumps Less Important Than Potholes For Graphene: Researchers have created detailed maps of electron interference patterns in graphene to understand how defects in the two-dimensional carbon crystal affect charge flow through the material. The results have implications for the design of graphene-based nanoelectronics.[2]
The Perfect Nanoballoon: How Ultrathin 'Graphene' Carbon Sheets Keep Everything Inside: Airtight containers are not always so airtight. As any child will discover the day after a birthday party, even a tightly tied helium balloon will leak its gas out over the course of many hours. Now scientists have come up with a supremely efficient barrier that lets nothing in or out.[3]
Graphene Used To Create World's Smallest Transistor: Researchers have used the world's thinnest material to create the world's smallest transistor, one atom thick and ten atoms wide. The smaller the size of their transistors the better they perform, say the Manchester researchers.[4]

Graphene Holds Promise For Spintronics: Graphene is a nanomaterial combining very simple atomic structure with intriguingly complex and largely unexplored physics. Since its first isolation about four years ago researchers suggested a large number of applications for this material in anticipation of future technological revolutions. In particular, graphene is considered as a potential candidate for replacing silicon in future electronic devices.[5]
