A New Path of Conduction for Future Electronics

From PhyOrg.com:

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.

Researchers Make Breakthrough in Nanotechnology by Uncovering Conductive Property of Carbon-based Molecules

Researchers Make Breakthrough in Nanotechnology by Uncovering Conductive Property of Carbon-based Molecules from PhysOrg.com

University of Pittsburgh researchers have discovered that certain organic—or carbon-based—molecules exhibit the properties of atoms under certain circumstances and, in turn, conduct electricity as well as metal. Detailed in the April 18 edition of Science, the finding is a breakthrough in developing nanotechnology that provides a new strategy for designing electronic materials, including inexpensive and multifunctional organic conductors that have long been considered the key to smaller, cheaper, and faster technologies.

A step toward circuits for terahertz computing

A step toward circuits for terahertz computing from PhysOrg.com

University of Utah engineers took an early step toward building superfast computers that run on far-infrared light instead of electricity: They made the equivalent of wires that carried and bent this form of light, also known as terahertz radiation, which is the last unexploited portion of the electromagnetic spectrum.

Information Storage in Three Dimensions

Information Storage in Three Dimensions from PhysOrg.com

For the first time, researchers have successfully turned a glass material into three-dimensional information storage using a light-based technique. This achievement may be a big step forward for the real-life implementation of such materials, which have the potential to store terabits of data (1,000 gigabits, or about 125 gigabytes) in just a single cubic centimeter.
