All-optical transistor created

Researchers from Germany’s Max Planck Institute of Quantum Optics (MPQ) and the Swiss Ecole Polytechnique Federale de Lausanne (EPFL) have created a microresonator that produces vibrations from laser light. The device also uses one laser beam to control the intensity of another, thus making it essentially an optical transistor. The technology could have big implications in fields such as telecommunications. Read More

Revolutionary diode design cracks 50 year-old electronics speed barrier

Metal-insulator-metal (MIM) diodes might just be the technology that allows electronics achieve the next big leap in processing speed. Research into diode design conducted at the Oregon State University (OSU) has revealed this week cheaper and easier to manufacture MIM diodes that will also eliminate speed restrictions of electronic circuits that have baffled materials researchers since the 1960's.

New graphene-based single-transistor amplifiers are a triple threat

Graphene has already brought us the world’s smallest transistortwice – and now the one atom thick form of carbon that recently won its discoverers the Nobel Prize has been used to create a triple-mode, single-transistor amplifier. The new transistor has the potential to replace many traditional transistors in a typical integrated circuit and its developers say the device could become a key component in future electronic circuits.

Silicon computer chips successfully implanted in living human cells

Scientists have begun integrating electronics into biology, but don't bolt your doors in fear of cyborgs and hybrid human-robots yet! Researchers from the Instituto de Microelectrónica de Barcelona IMB-CNM (CSIC), have found a way to implant minute silicon chips into living cells and use them as intracellular sensors. This bio-nanotechnological advancement could tell us a lot about how our cells are working at a nano level, and have widespread implications for early detection of diseases, and new cellular repair mechanisms.

Toshiba's spintronics transistor and a new storage mechanism in silicon come to life

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.

Single-atom transistor promises new quantum computing breakthroughs

As far as transistor size is concerned, it doesn't get any smaller than this. An international group of researchers from the Helsinki University of Technology, the University of New South Wales and the University of Melbourne have successfully built a fully working transistor that is just one atom in size, smashing previous records and, more importantly, creating a very unique venue to study phenomena to be exploited in the rapidly developing field of quantum computing.

Nanowires could be the key to the transistors of tomorrow

Researchers agree that chip manufacturers will soon reach a hard limit in terms of transistor miniaturization, disproving rule-of-thumb predictions that transistor density roughly doubles every 18 to 24 months. But a collaboration between IBM, Purdue University and the University of California in Los Angeles may have found a way to squeeze more transistor in the same area by building them vertically rather than horizontally.
