Graphene is widely regarded as the electronics material of the future, but in an article published over the weekend in the journal Nature Nanotechnology, a group from EPFL’s Laboratory of Nanoscale Electronics and Structures (LANES) describes how the abundant mineral molybdenite (MoS2) is a very effective semiconductor with advantages over both graphene and silicon. The discovery could allow for transistors that are smaller and orders of magnitude more efficient.
Electronic devices could get much more sophisticated with new diode technology that allows electrons to move around more quickly. Two groups of researchers are reporting advances in diode performance through new manufacturing processes — one uses a metal-insulator-metal system and another uses metamaterials to work with electromagnetic waves. The new systems could yield a new approach to electronics, researchers say.
In a discovery sure to help the development of solar panel and display technology, scientists at the National Institute of Standards and Technology (NIST) have engineered transistors that they can airbrush onto a surface like spray paint.
One squat multitasking robot can build semiconductors for solar cells on six-inch-square plates of glass, plastic or flexible metals in just over half an hour. Six of these tireless mechanical workers, chugging away at the National Renewable Energy Laboratory (NREL) in Colorado, will allow private companies to come rapidly prototype and test their newest formulas for creating solar cells.
Transistor junction, what's your function now? Irish researchers at the Tyndall National Institute have fabricated the world's first junctionless transistor, a nanotech development that could change the way semiconductors are manufactured.
Ask a GM employee, any barstool economist, or your dad, and they'll all likely tell you the same thing: American manufacturing ain't what she used to be. But who will think us out of this economic box we've trapped ourselves in? DARPA, of course. DARPA's director told the President's Council of Advisors on Science and Technology (PCAST) that by replicating the successful model that the semiconductor industry is built upon, other manufacturing sectors can experience similar booms as well.
Moore's Law provides the axiom that the number of transistors that can be placed on a circuit will double every two years, but as we reach for smaller and smaller tech, silicon and other transistor materials are reaching their physical limits. Lucky for Moore, a European research group has produced graphene of a size and quality that can be practically developed for eventual commercial use.
What happens when you add 64,000 tiny components to a base of oil and water? Depending on the nature of the components, you might end up with a delectable vinaigrette. University of Minnesota researchers found something even more tantalizing: a self-assembly method that is particularly effective at joining extremely small components in electronic devices.
