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.Read More

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.Read More

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.Read More

Quantum computer closer: Optical transistor made from single molecule

Quantum photonics is a particularly attractive field to scientists and engineers alike in that it could, once some core issues have been resolved, allow for the production of integrated circuits that operate on the basis of photons instead of electrons, which would in turn enable considerably higher data transfer rates as well as dramatically reduced heat dissipation. Now in yet another important achievement on the road to quantum computing, researchers from ETH Zurich have managed to create an optical transistor from a single molecule.Read More

World’s thinnest material used to create world's smallest transistor

April 21, 2008 In recent decades, manufacturers have crammed more and more components onto integrated circuits, roughly keeping pace with Moore’s Law. But for this to continue the semiconductor industry must overcome the poor stability of materials if shaped in elements smaller than 10 nanometres in size. At this spatial scale, all semiconductors, including silicon, oxidize, decompose and uncontrollably migrate along surfaces like water droplets on a hot plate. Now researchers at the University of Manchester, reporting their peer-reviewed findings in the latest issue of Science, have shown that it is possible to carve out nanometre-scale transistors from a single graphene crystal. Unlike all other known materials, graphene remains highly stable and conductive even when it is cut into devices one nanometre wide.Read More

Intel release eco-friendly, high-performance 45nm processors

November 13, 2007 Intel has unveiled sixteen new chips incorporating 45nm Hafnium-based high-k metal gate transistors that are smaller, faster and more eco-friendly than previous generations. Gordon E. Moore, co-founder of Intel, has labeled the breakthrough as the biggest transistor advancement in 40 years with the improvement expected to further extend Moore’s Law, which he originally described in 1965.Read More
