标题: Konstantin Novoselov 和 Andre Geim 凭借超薄碳物质获得诺贝尔物理学奖

Konstantin Novoselov and Andre Geim of the University Of Manchester have won a Nobel for their creation of Graphene. This project first became public in 2004 when they were able to demonstrate electronic effects with ultra thin sheets of carbon that they created by “mechanical exfoliation … of small mesas of highly oriented pyrolytic graphite.”

Graphene is one of the most exciting new compounds as it can be used in so many ways. To hear that it started with a strip of Scotch tape is fascinating.

This image of a carbon nanotube made from graphene was created using a scanning tunneling microscope. The reddish objects are individual carbon atoms, with dark hexagonal holes between atoms.

Atom for Atom, graphene has developed into something 100 times stronger than steel, primarily because the single layered atoms are bonded together in a honeycomb lattice structure. A one thick sheet is not that tough, however when they are combined into composites the end product could be many times stronger than even Kevlar. The possibility of using this material for light weight body armor or for vehicle chassis is staggering.

On a technological level, the graphene sheets can be made thin enough to be used in laptop and television screens. Researchers have said that they have already created a working touch screen display using graphene.

It may be some time before silicon would be under threat however electricity flows easily through graphene without losing much energy en route. Scientists are currently working to incorporate it with other elements which would pave the way for ultra thin, ultra fast circuitry. IBM have already demonstrated a graphene based transistor which operates 10 times faster than the fastest silicon chip. If Moore’s Law is to continue then we will certainly need to be looking outside the realms of silicon.

After scooping the £1 million Nobel prize money Geim told Reuters “I would compare this situation with the one 100 years ago when people discovered polymers. It took quite some time before polymers went into use in plastics and became so important in our lives.”

新闻里面说的一个原子大的碳石墨材料，是吧

激动啊石墨稀带来电子工业革命

什么物质都没用，10nm之前靠大马士革，1nm之前靠自旋电子，超过1nm你就是在管上种出花来也是无济于事
半导体业界目前的问题，甚至在触及到衍射极限前的所有问题基本上都无法靠石墨烯来解决。虽然有人提出过利用石墨烯来改善刻蚀，但明显这么搞的意义还不如拿它来改善界面问题来得实在
这玩意的妙处其实是在于表面和界面，只要你有足够的想象力，你甚至可以用它在凝聚态之类的场合做任何事情。再就是可以让人们重新审视热力学体系，毕竟过去谁都觉得热力学涨落会毁掉任何二维晶体结构，而石墨烯则给人们来了一记回旋踢打脸……
对于半导体领域来说，虽然所有人都知道存在可能性，但二维晶体与门电路结构之间确实还没有什么可见的实际联系，基本上现阶段还停留在宣传和方便科普（忽悠）公众的程度。所以最近几年基本上碰到说什么可能带来半导体业革命的时候，看个乐呵就成了

厄……扯了这么多蛋，似乎跟显卡没啥联系……

这个拿诺贝尔太不靠谱了，压根都没用上的东西，而且出来也没几年

光忒快了，没办法用来计算，只能用来传输。
不过实现芯片内的光传输是真正革命性的技术。
