Spintronics: Silicon twists
Abstract
For decades, silicon has been the dominant material for conventional, charge-based electronics. A new twist makes silicon ripe to enter the domain of spintronics, where the new currency is electron spin.
Modern computers present serious challenges for conventional, silicon-based electronics. Ever-increasing demands on processor speed, memory storage and power consumption — the era of the laptop that can keep us warm in winter is fast upon us — are forcing researchers to explore unfamiliar territory in the quest for increased performance.
