Solid-state physics: Recipe for spin currents
N. P. Ong1
Abstract
Generating currents that rely on the spins of electrons to make electronic devices requiring less power is both desirable and daunting. A neat way of creating such currents eases that task.
The field of spintronics — spin electronics — seeks to harness the spin of electrons in metals and semiconductors in order to perform tasks that are, at present, routinely carried out by electrons' charge. Spintronics offers a promising path to achieve further reduction in both the size and power consumption of solid-state devices.
