How electrons conduct electricity depends on their valley

To meet demand for smaller, more powerful electronics, engineers are struggling to find ways to store more information in a smaller area. Today’s computers store information digitally as a series of 1’s and 0’s using two fundamental properties of electrons: their charge (which enables flash drives) and their spin (which enables hard disks). To date, advances in digital storage have relied on a simple approach: writing smaller 1’s and 0’s.

  A recent breakthrough at Cornell University may enable a different approach.

Esoteric property of topological insulators leads to efficient switching

 

Physicists have been abuzz over a new state of matter — a ‘topological insulator.’ These materials are insulators in their interior, but their surfaces conduct electricity in an unusual way: the direction of an electron’s spin is always perpendicular to the direction of the electron’s motion as sketched at right. But is this esoteric property useful for anything?
