One Step Again, Graphene Magic Material in Your Smartphone - Begin to imagine your smartphone in the grip of a few tens of times lighter, but 200 times stronger than steel.
All that will happen in the next few years, following the statement of the Samsung Advanced Institute of Technology who successfully developed a new transistor structure using graphene.
One Step Again, Graphene Magic Material in Your Smartphone
Found by Andrei Geim and Konstantin Novoselov in 2004, graphene - a material often called magic (miracle material) - is the strongest material on earth. At least 20 times stronger than diamond, 200 times stronger than steel and six times lighter, and highly conductive - both electrically and thermally.
Still not enough, graphene is nearly transparent, gas-tight, and - according to some scientists - easy to set up.
Thanks to its findings, Geim and Novoselov awarded the Nobel Prize in physics in 2010. Yet since the findings were published, the whole country racing to research and development to produce graphene commercial scale, and use them in all electronic and aviation industries.
Graphen has electron mobility about 200 times greater than silicon. However, the development of graphene as a replacement for silicon knock the fact that transistors made from graphene can not be turned off. Graphene is a semi-metallic material.
Samsung Advanced Institute of Technology reengineer the basic operating principles of digital switches, and successfully developed a device that turns off the transistor made from graphene without degrading its mobility. This device is called Barristor.
So far, Samsung Advanced Institute of Technology has registered nine findings to the world patent offices, which are all related to graphene. Special methods of operation Graphene Barristor, these findings make Samsung leading in the development of graphene.
Peng Sheng, professor of nanoscience at the Hong Kong University of Science and Technology, said graphene has a lot of potential, especially in the industrial application of optical and electronic devices.
Sheng believes will not be long before many plants will produce commercial-scale graphene, and the electronics industry to use it.
