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
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.
By manipulating matter at the nanoscale level, engineers from North Carolina State University led by Dr. Jagdish Narayan have developed a new material that could make it possible to manufacture terabyte memory chips the size of a fingernail, boost vehicles' fuel economy significantly and reduce heat dissipated by semiconductors, with applications ranging from spintronics
to solar panel technology.
While working on their long-term goal of achieving a true quantum computer, a team of researchers from Stanford University, the Joint Quantum Institute, MIT and Texas A&M University has recently discovered that tiny nitrogen impurities in diamonds make outstanding magnetic probes in the cellular and molecular scale, with important applications that could truly benefit medical research.
How often do you find yourself with a portable computer burning up on your lap with strange noises coming from your fan? Thanks to a recent research conducted at Stanford University, bismuth telluride — a new, easy-to-manipulate material with unique electrical properties — could make computer fans a distant memory while allowing for much faster and power-efficient devices. Move over electronics - here comes spintronics.
