Latest Topological insulator Stories
An odd, iridescent material that's puzzled physicists for decades turns out to be an exotic state of matter that could open a new path to quantum computers and other next-generation electronics.
University of Utah engineers discovered a way to create a special material – a metal layer on top of a silicon semiconductor – that could lead to cost-effective, superfast computers that perform lightning-fast calculations but don’t overheat.
Research into a recently discovered class of materials shows they have the necessary characteristics to develop ultra-energy efficient electronics. Topological insulators (TI) are three-dimensional materials that conduct electricity on their surfaces, while the interior insulates.
Topological insulators — materials whose surfaces can freely conduct electrons even though their interiors are electrical insulators — have been of great interest to physicists in recent years because of unusual properties that may provide insights into quantum physics.
The discovery of what is essentially a 3D version of graphene – the 2D sheets of carbon through which electrons race at many times the speed at which they move through silicon – promises exciting new things to come for the high-tech industry, including much faster transistors and far more compact hard drives.
Theorists Predict New Single-Layer Material Could Go Beyond Graphene, Conducting Electricity with 100 Percent Efficiency at Room Temperature
Topology -- the understanding of how things are connected -- remains abstract, even with the popular example of doughnuts and coffee cups.
Imagine if the "information superhighway" had HOV lanes so that data could be stored, processed and disseminated many times faster than possible with today's electronics.
Berkeley Lab scientists discover how a photon beam can flip the spin polarization of electrons emitted from an exciting new material
