spin — Wed, 04 Nov 2009 06:31:29 +0000

A must-have ten-volume successor to the critically acclaimed Nanotechnologies for the Life Sciences series, Magnetic Nanomaterials is as a cross-disciplinary reference that provides an excellent, in-depth overview of all nanomaterial types and their uses in the life sciences. Each volume is dedicated to a specific material class and covers fundamentals, synthesis strategies, structure-property relationships, material behavior fine-tuning, biological effects, and applications in the life sciences. This landmark publication provides materials scientists, chemists, biologists, molecular biologists, clinical physicists, physiological chemists, medicinal chemists, and toxicologists with essential awareness of life science and nanomaterials abilities.

The NSF granted 450,000 US$ for spintronics research

spin — Fri, 30 Oct 2009 06:36:31 +0000

The National Science Foundation (NSF) has granted $450,000 to a pair of Florida State University scientists to perform advanced measurements on semiconductors developed by colleagues in China. Their goal is to determine whether electron spin can be harnessed in such a way that future computers and other high-tech electronic devices would require far less power to run.

Researchers developed a way to control electron spin using pure-electric means

spin — Thu, 29 Oct 2009 08:24:29 +0000

Researchers from the University of Cincinnati has developed a novel way to control the spin of electrons using pure electric means. Before the researchers made their breakthrough, the only way to control the spin of electrons was by using local ferromagnets in device architectures. The scientists say that this technique results in design complexities when the demands for electronics require smaller and smaller transistors.

The team used a device called a quantum point contact. Philippe Debray, research professor in the Department of Physics in the McMicken College of Arts & Sciences said "We used a quantum point contact — a short quantum wire — made from the semiconductor indium arsenide to generate strongly spin-polarized current by tuning the potential confinement of the wire by bias voltages of the gates that create it."

Korean researchers created the first first spin field-effect transistor

spin — Sun, 20 Sep 2009 10:15:22 +0000

A team of Korea Institute of Science and Technology (KIST) researchers led by Han Suk-hee described the demonstration of a spin-injected field effect transistor, which is based on a semiconducting channel with two ferromagnetic electrodes.

The transistor's basic structure of source, gate and drain is similar to the complementary metal-oxide-semiconductor (CMOS) model used for making microprocessors and other integrated circuits. However, Han's transistor is different in that the source and drain are made of ferromagnetic materials and that the injected spins are controlled by gate voltage.

North Carolina Stata University gets a 1.2M$ grant to work on molecular spintronics

spin — Thu, 17 Sep 2009 08:10:43 +0000

Researchers at North Carolina State University have received a three-year, $1.2 million grant from the National Science Foundation’s Center for Chemical Innovation (NSF-CCI) to pursue research in the emerging field of molecular spintronics.

The grant will fund a center for molecular spintronics at NC State and support a research coalition between scientists at NC State and UNC-Chapel Hill with the aim of using this technology to develop smaller, faster, more energy-efficient electronic devices with increased storage capability.

Researchers make semiconductor crystals (nanocrystals, or quantum dots) display new magnetic functions at room temperature

spin — Fri, 28 Aug 2009 18:00:53 +0000

Researchers in the University of Washington say that they have been able to train tiny semiconductor crystals, called nanocrystals or quantum dots, to display new magnetic functions at room temperature using light as a trigger.

Silicon-based semiconductor chips incorporate tiny transistors that manipulate electrons based on their charges. Scientists also are working on ways to use electricity to manipulate the electrons' magnetism, referred to as "spin," but are still searching for the breakthrough that will allow "spintronics" to function at room temperature without losing large amounts of the capability they have at frigid temperatures.

QuantumWise releases new version of their simulation software
