Topological Insulators News
Topological insulators are a class of materials that behave as insulators in their interior but conduct electricity on their surface. This unique property is due to the material’s electronic structure, which results from strong spin-orbit coupling and time-reversal symmetry. On the surface of these materials, electrons can move without resistance, and they are not affected by defects or impurities. This makes topological insulators very promising for applications in quantum computing and spintronics. The surfaces of topological insulators host exotic states where the spin of electrons is locked to their direction of motion, a phenomenon that could lead to new ways of manipulating electronic properties for technological advances. These materials are also explored for potential use in creating more efficient electronics and advancing quantum information technology.
