New Structure for the Electron Highway
Researchers at the University of Würzburg have developed a topological insulator that works at higher temperatures, overcoming the limitation of functioning only at very low temperatures.
A topological insulator is a material that is a perfect insulator on the inside and does not conduct electricity, but at its edges, it behaves like an almost lossless "electron highway".
Electrons can move along these paths with almost no loss.
The "electron highway" has separate lanes for electrons with different "spins", preventing collisions and energy losses, with "spin-up" electrons moving in one direction and "spin-down" electrons in the opposite direction.
Author's summary: New topological insulator works at higher temperatures.
