From The New York Times:
Hewlett-Packard scientists on Thursday are to report advances in the design of a new class of diminutive switches capable of replacing transistors as computer chips shrink closer to the atomic scale.Full article
From PhysOrg.com:
Scientists have leaped over a major hurdle in efforts to begin commercial production of a form of carbon that could rival silicon in its potential for revolutionizing electronics devices ranging from supercomputers to cell phones. Called graphene, the material consists of a layer of graphite 50,000 times thinner than a human hair with unique electronic properties. Their study appears in ACS' Nano Letters.Full article
From PhysOrg.com:
University of Queensland researchers have successfully demonstrated a futuristic semiconductor technology that will pave the way for the next generation of electrical and information technology systems.Full article
From PhysOrg.com:
In a just-published paper in the magazine Science, IBM researchers demonstrated a radio-frequency graphene transistor with the highest cut-off frequency achieved so far for any graphene device - 100 billion cycles/second (100 GigaHertz).Full articke
From PhysOrg.com:
MIT researchers have demonstrated the first laser built from germanium that can produce wavelengths of light useful for optical communication. It’s also the first germanium laser to operate at room temperature. Unlike the materials typically used in lasers, germanium is easy to incorporate into existing processes for manufacturing silicon chips. So the result could prove an important step toward computers that move data -- and maybe even perform calculations -- using light instead of electricity. But more fundamentally, the researchers have shown that, contrary to prior belief, a class of materials called indirect-band-gap semiconductors can yield practical lasers.Full article

A new approach in the design of miniature, insectlike robots could lead to "microids" the size of ants that move their tiny legs and mandibles using solid-state "muscles."Full article
From PhysOrg.com:
Scientists at Rice University and North Carolina State University have found a method of attaching molecules to semiconducting silicon that may help manufacturers reach beyond the current limits of Moore's Law as they make microprocessors both smaller and more powerful.Full article
Researchers report finer lines for microchips: Advance could lead to next-generation computer chips, solar cells from PhysOrg.com
MIT researchers have achieved a significant advance in nanoscale lithographic technology, used in the manufacture of computer chips and other electronic devices, to make finer patterns of lines over larger areas than have been possible with other methods.

Quote: "The new method could make possible the commercialization of many new nanotechnology inventions that have languished in laboratories due to the lack of a viable manufacturing method."
Trap and zap: Harnessing the power of light to pattern surfaces on the nanoscale from PhysOrg.com
Princeton engineers have invented an affordable technique that uses lasers and plastic beads to create the ultrasmall features that are needed for new generations of microchips.

'N-variant' microchips could protect intellectual property, enable new services from PhysOrg.com
Rice University computer engineers have created a way to design integrated circuits that can contain many multiple selves. The chips can assume one identify or a subset of identities at a time, depending on the user's needs. New research shows that multiple "personalities" in an integrated circuit can be even a more powerful security mechanism that can be used for a variety of digital rights management tasks as well as for circuit optimization and customization without sacrificing the related power, delay and area metrics.

Rensselaer student invents alternative to silicon chip from PhysOrg.com
Even before Weixiao Huang received his doctorate from Rensselaer Polytechnic Institute, his new transistor captured the attention of some of the biggest American and Japanese automobile companies. The 2008 graduate’s invention could replace one of the most common pieces of technology in the world—the silicon transistor for high-power and high-temperature electronics.

Engineers demonstrate nanotube wires operating at speed of commercial chips from PhysOrg.com
Integrated circuits, such as the silicon chips inside all modern electronics, are only as good as their wiring, but copper conduits are approaching physical performance limitations as they get thinner.

Move over, silicon: Advances pave way for powerful carbon-based electronics from PhysOrg.com
Bypassing decades-old conventions in making computer chips, Princeton engineers developed a novel way to replace silicon with carbon on large surfaces, clearing the way for new generations of faster, more powerful cell phones, computers and other electronics.
