A New Path of Conduction for Future Electronics


Last month, researchers from SLAC National Accelerator Laboratory made headlines when they revealed experimental evidence of a topological insulator: a material that could revolutionize computer processors by allowing electricity to flow without resistance. This week in Science, SLAC theorists along with an experimental group in Germany report additional details about the way these topological insulators conduct electricity. Using the topological insulator mercury telluride, the paper shows that an electric current sent through these materials goes against conventional physics knowledge and travels far away from its input points, to the outer edges of the material.
