Spintronics

The superfast computers of tomorrow will likely be able to manipulate individual electrons, harnessing their charge and magnetism to achieve massive data storage and outstanding processing speeds at very low power requirements. But how exactly do you go about manipulating single electrons independently, without affecting the ones nearby? Princeton University's Jason Petta has recently demonstrated a way to do just that in a breakthrough for the field of spintronics that brings faster and low-power number-crunching closer to reality.

In a recent issue of the journal Nature, researchers from the University of Twente, Netherlands, explain how they succeeded in transferring magnetically coded information directly into a semiconductor, for the first time at room temperatures. Meanwhile, Toshiba announced at the International Electronics Devices Meeting (IEDM) it has developed a MOSFET transistor harnessing spintronics, demonstrating stable, fast and low-power performance.

Scientists at UC Santa Barbara have made important advances in the field of spintronics by demonstrating the ability to electrically manipulate, at room temperatures, the quantum states of electrons trapped in the atomic structural defects of diamond crystals. Despite previous indications to the contrary, such quantum states can be manipulated very quickly, even at gigahertz frequencies, paving the way to significantly faster quantum computing. Read More
A team of researchers from the University of Cincinnati have achieved control of the spin of electrons traveling on a wire by simply regulating an electrical voltage. This is a major milestone in the brief history of spintronics, the emerging technology that uses the spin of electrons to store and manipulate digital information with much higher speeds and efficiency.
