Need Ultrafast Information Processing? Try Topological Materials for Ultrafast Spintronics
The laws of quantum physics rule the microcosm. They determine, for example, how easily electrons move through a crystal and thus whether the material is a metal, a semiconductor or an insulator. Quantum physics may lead to exotic properties in certain materials: In so-called topological insulators, only the electrons that can occupy some specific quantum states are free to move like massless particles on the surface, while this mobility is completely absent for electrons in the bulk.

Beginner’s Guide to Topological Materials
Ever since a new class of materials called topological insulators was first created—a discovery that helped win the Nobel Prize in Physics in 2016—researchers have been intrigued by the possibilities for electronics applications such as ultralow-energy transistors, cancer-scanning lasers, and free-space communication beyond 5G. Topological insulators’ unusual name stems from their being insulating on the inside and conductive on the outside: […]
Quantum Hall Edge States Defying the ‘Normal’ Disturbances, U.S NIST Investigates
NIST team probes indestructible quantum states that may aid quantum computing They may not be impervious to bullets like Superman, but groups of electrons that gather along the edges of some ultrathin materials have their own superpowers. Defying such disturbances as bending, stretching, the introduction of an external magnetic field, and distortions that wreck the […]
