British scientists found faster than the optical fiber transmission medium

Recently, British scientists discovered a far more efficient than current optical fiber technology, communication media material - graphene, graphite combined with a plasma of
this tiny metal nano-structure can be faster than the fastest fiber tens to hundreds of times .


Graphene is a two-dimensional crystals, the biggest feature is one of the electron velocity to the speed of light in 1 / 300, far more than an electronic conductor in the normal

velocity. This makes graphene electronics, or more accurately, should be called "charge carriers" (electric charge carrier), and the relativistic nature of neutrinos is very

similar. It is a common graphite with honeycomb layers of ordered carbon atoms of the plane formed by stacking, weak forces between layers of graphite, it is easy to peel each

other to form a thin graphite film. When the film strip into a single layer of graphite, after this there is only one carbon atom thick graphene monolayer is.

It was found that graphene has unusual electrical properties, exceeding the number of times the strength of steel and excellent light transmission, it appears the field of

modern electronic technology is expected to lead to a revolution. In graphene, electrons can move very efficiently, while the traditional semiconductors and conductors, such as

silicon and copper is far from good performance of graphene. As the electronic and atomic collisions, the traditional semiconductor and conductor with the release of some form

of heat energy, the current general computer chips in this way a waste of 70% -80% of the electricity, graphene is different, its electronic energy is not will be losses, which

it has an unusually fine features.

Graphene can also look to photonic sensors on the market in larger, this sensor is used to detect the information carried by optical fiber, and now, this role is also played by

the silicon, but silicon era seems to end. Last October, IBM's disclosure of a research team for the first time they developed graphene photodetector, then it is to expect

graphene-based solar cells and liquid crystal display has. Because graphene is transparent, it made panels than other materials, has better light transmission.

I believe in the near future is bound to promote the development of optical transmission technology, if the application can then be launched to the optical communications

industry, the new revolution.
