A Beginner’s Guide to Topological Materials
Emily Cooper The topological material tantalum arsenide generates tremendous current (small arrows) upon illumination. 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 […]
