Stanford researchers proposed a new method of assembling elektropovodnikov
Scientists from Stanford University and the US Department of Energy have developed a method for the production of extremely thin electrical conductors with extraordinary properties. Based diamondoidov - polymeric organic molecules in which carbon atoms of the skeleton are interconnected in the same way as in the fragments of the diamond crystal lattice, - researchers were able to create elektroprovdniki thickness of only three atoms. On the basis of such conductors in the future it will be possible to create, for example, a fabric that will conduct electricity without energy loss.
Connect conductors such microscopic between a method similar to the assembly LEGO constructor. The process starts with the compound with the sulfur atom diamondoidom. Each sulfur atom in turn creates a chemical compound with the copper ion. From the outside it seems to be picking up the connection designer, hence the reference to LEGO. Due to the attraction between diamondoidami, "cubes" designer come together and create a solid conductor.
Despite the apparent complexity of the assembly, in fact, the process of creating such conductors takes relatively little time. To create a superfine wire takes only about half an hour. The new assembly method has other advantages. Attractive properties diamodoidov allow scientists to create tiny wires with amazing accuracy - atom by atom - and getting results that could not be achieved in any other case.
"Just like LEGO blocks, the conductor can only connect in a certain way, taking into account the size and shape of the parts. Inside each conductor are sulfur atoms and copper, acting as a conductive medium. From diamodoidov in turn consists of the wire, "- explains graduate student at Stanford University and one of the key researchers to synthesize the wires, Fei Hua Li.
Despite the early stage of development, the results are very intriguing. Once on the basis of such electrical conductors will be possible to create new materials with electrical properties. Guides, allowing to conduct electricity without any loss of power may be the beginning of a new level of efficiency of the electrical conductivity.
