Physicists at BESSY II have investigated a class of materials that exhibit characteristics of topological insulators. During these studies, they discovered a transition between two different topological phases, one of which ...
A new method that precisely measures the mysterious behavior and magnetic properties of electrons flowing across the surface of quantum materials could open a path to next-generation electronics.
Topological insulators, materials that insulate on the inside but conduct electricity along their outer edges, have created quite a buzz in condensed matter physics. Now a new study in the journal Science shows that the same ...
Topological insulators, a class of materials which has been investigated for just over a decade, have been heralded as a new 'wonder material", as has graphene. But so far, topological insulators have not quite lived up to ...
For the last decade, scientists have sought topological insulators, materials that are insulating on the inside but conduct current on their surfaces. Although first predicted around 2005, very few real-world examples have ...
In 1928, physicist Paul Dirac made the stunning prediction that every fundamental particle in the universe has an antiparticle – its identical twin but with opposite charge. When particle and antiparticle met they would ...
An international team of researchers has found a way to determine whether a crystal is a topological insulator—and to predict crystal structures and chemical compositions in which new ones can arise. The results, published ...
It's ultra-thin, electrically conducting at the edge and highly insulating within—and all that at room temperature: Physicists from the University of Würzburg have developed a promising new material.
Researchers at the University of Illinois at Urbana-Champaign and Princeton University have theoretically predicted a new class of insulating phases of matter in crystalline materials, pinpointed where they might be found ...
A group of physicists from MIPT and the Landau Institute for Theoretical Physics of the Russian Academy of Sciences are now one step closer to finding applications for topological insulators—materials with remarkable electrical ...
