 The scanning electron microscope can be seen that temperature gradient is built up in the graph produced in silica. The graph is better able to dissipate heat from electronic circuits than copper. The new research shows. The result could be a new industry standard. The super-graph material is extremely successful at driving away the heat has long been known. The material has therefore been a given candidate to lead off the increasing heat generated as the transistors are packed closer and closer to circles. And that threatens to destroy them. But until now scientists did not know about the good heat conducting ability of the graph is added to the substrate in which circuit boards are manufactured on. How it is the case, the U.S. researchers, led by Jae Hun Seol at the University of Texas at Austin, the answer to. Their research has shown that graph, which is placed on silicon, at room temperature has a thermal conductivity of 600 watts per meter per Kelvin. Although it is five times lower than the one atomic layer thin layer of carbon is when it is for himself, but it is nevertheless higher than the heat conductivity of copper (which is 401 watts per meter Kelvin). According to the researchers suggest the results against the graph may be more useful in electronics than the current industry standard, and that the material could compete out the copper in the case to divert heat from electronic circuits. The researchers' results are presented in today's issue of the journal Science. |
