Topological insulators generally function at very low temperatures, limiting their practical application.
Researchers at the University of Würzburg have developed a topological insulator that works at higher temperatures.
A topological insulator is a material that is a perfect insulator on the inside, but behaves like an almost lossless "electron highway" at its edges.
Electrons can move along these paths with almost no loss.
These highways have separate lanes for electrons with different "spins", preventing collisions and energy losses.
Author's summary: New topological insulator works at higher temperatures.
