Circuits that love heat.
The carbide of silicon, a crystalic material almost as hard as diamond, could be used in electronic circuits that function more rapidly and more efficiently and remain invulnerable in the heat and the radiation.
In relation with the current circuits from silicon, the chips from carbide of silicon would have up to 70% smaller consumption of energy and would not require air fans or other systems of cooling. The carbide of silicon is in deed so much refractory that it could be placed directly in engines or in nuclear reactors!
Japanese researchers of Toyota report now in Nature that they discovered a method for the production of almost perfect crystals from carbide silicon in large size, up to seven centimeters.
The carbide of silicon cannot simply melt and be poured in moulds. Its crystals must be produced by the condensation of vaporized carbide of silicon. However between the thin layers that the vaporized material shapes imperfections are created that disturb the flow of electrons and they render the crystal inadequate for use in the Electronics.
The team of Daisuke Nakamura in the Central Laboratories of Research and Technology of Toyota developed a method for the condensation of repeated layers in which any imperfections that are created are removed and the process continue.
Nakamura clarifies that until the material passes in the process of production further researches are required, however he believes that the first chips from carbide of silicon will be presented in the market in roughly six years and will change completely the world of electronics, computers and mobile technology as we know.
