When Andre Geim and Konstantin Novos, University of Manchester developed graphene, won the Nobel Prize in Physics. This element has a border width of an atom, is one of the lighter materials, more conductive, and resistant to the ground. Among the various applications that can develop graphene, are DNA sequencing and construction of a medium with an extraordinary capacity for energy storage. But how can a computer of this material? Well ... just add water .
Graphene is a flat sheet structure of an atom thick, composed of carbon atoms densely packed in a network crystalline form of honeycomb through covalent bonds that are formed from the overlap of sp hybrid 2 bonded carbons.
The name comes from GRAPHITE + ENO . In fact, the graphite structure can be considered as a stack of a large number of overlapping graphene sheets. The links between the stacked layers of graphene due to Van der Waals forces and interactions between the n orbitals of carbon atoms.
Well, now a group of researchers from Rensselaer Polvtechni University has achieved remarkable progress in the use of graphene as a material for making transistors, thereby have placed the next generation of computers, virtually the hand.
Professor Nikhil Koratkar and his team have published their discovery in a paper entitled "Tunable Bandgap in Graphene by the Controlled Adsorption of Water Molecules - Banda adjustable graphene by absorbing water molecules - . In other words, without need for expertise in Advanced Physics, it would simply be used in conjunction with water to create a graphene transistor.
Y. .. How would a transitor of these features? If we put a plate on graphene a silicon and silicon dioxide, sending water through the small space between the two, the liquid moves away from the silicon to the graphene by stopping the conduction of water and breaking the connection. This is important because water is a safe and common element, so when this technology take off, you need less toxicity than that produced with the current transistors.
tangible and immediate thing is that graphene can be solved in the short term, total connectivity problems. In combination with the possibilities dramatically higher storage, graphene transistor has the potential to make computers more resilient, much smaller and much faster than we have today. For example, a device the size of a tablet may have the processing power and memory of an entire computer network.
Now .... Imagine having a portable graphene, a material capable of becoming, because it is transparent monitor-and processor-ten times faster than silicon, which in turn, rolled and folded, which is as unbreakable as diamond and ... which has only one atom thick!
