MORE CARBON INSTEAD SILICON


The russian Igor Lukyanchuk (Physicist/University of Picardie/Amiens), said that the power of the PC could multiply for 1000, if silicon is replaced by graphite (crystalline form of carbón). In the 2004, Lukyanchuk, working with the physicist Yakov Kopelevich (University of Campinas/São Paulo, Brazil), discovered a remarkable property of the graphite: some electrons behave as photons, close to the superconductivity phenomenon (capacity of certain materials to drive electric current without resistance). Aart from being able to manufacture fleas, it would be possible with the aid of grafenos : to carry out simultaneous translations of voices, to compress pictures in but efficient form and to increase the power of calculus. In 2005, André Geim (University of Manchester) and Philip Kim (University of Columbia), isolated leaves of graphene ,with only 2 measurementss (long and wide) with diameter of the size of graphite atoms (angstroms), below the scale of the nanometer (10-9m), gestating a new electronics, with the carbon instead of silicon. While DARPA, tries to obtain a grapheno movie (50 mm x 50 mm), Geim dreams of manufacturing the first graphene transistor.
MORE CARBON INSTEAD SILICON

El ruso Igor Lukyanchuk (Physicist/University of Picardie/Amiens), sostiene que el poder de las PC podria multiplicarse por 1000, si se reemplaza el sílicio por grafito (forma cristalina del carbóno). En el 2004, Lukyanchuk, de conjunto con el físico Yakov Kopelevich (Universidad de Campinas/São Paulo, Brasil), descubrieron una notable propiedad del grafito : algunos electrones se comportan como fotones, fenómeno cercano a la superconducitividad (capacidad de ciertos materiales para conducir corriente eléctrica sin resistencias de por medio. Aparte de poder manufacturar pulgas, seria posible con la ayuda de grafenos realizar traducciones simultanea de voces, comprimir fotos en forma mas eficiente e incrementar el poder de cálculo. En el 2005, André Geim (University of Manchester) y Philip Kim (University of Columbia), aislaron hojas de grafeno de solo 2 medidas (largo y ancho), cuyo grosor es del tamaño de atomos de grafito (angstroms), por debajo de la escala del nanometro (10-9m), gestando una nueva electronica, con el carbon en lugar del silice. Mientras la Darpa, trata de obtener una pelicula de grafeno (50 mm x 50 mm), Geim sueña con manufacturar el primer transistor de grafeno.
