Single-molecule switch An international team of researchers have demonstrated a switch on a single fullerene molecule. Using a laser, the team switched the path of an incoming electron. “What we’ve managed to do here is control the way a molecule directs the path of an incoming electron using a very short pulse of red laser light,” said Project Researcher Hirofumi Yanagisawa from the Uni... » read more

The Challenge: By 2020, Cisco forecasts that 5.5 billion people will own mobile phones. In the United Kingdom alone, tens of millions of these mobile users will each consume 20 GB of data per month and use more than 25 different smart devices in their daily routines. Factor in data-hungry applications like 4K video, driverless vehicles, smart factories, and broadband access expanding to the mos... » read more

TFETs Cut Sub-Threshold Swing
By Katherine Derbyshire - 16 Mar, 2017 - Comments: 0

One of the main obstacles to continued transistor scaling is power consumption. As gate length decreases, the sub-threshold swing (SS) — the gate voltage required to change the drain current by one order of magnitude — increases. As Qin Zhang, Wei Zhao, and Alan Seabaugh of Notre Dame explained in 2006, SS faces a theoretical minimum of 60 mV/decade at room temperature in conventional MO... » read more

Preparing For 5G
By Jeff Dorsch - 09 Aug, 2016 - Comments: 0

If you like 4G LTE, you’re going to love 5G. The next-generation wireless communications technology will offer faster data transmission speeds and lower latency, providing the processing power to drive augmented-reality and virtual-reality applications for mobile devices and dedicated headsets. There is a caveat, though. The world needs to develop a consensus on what the 5G spectrum wil... » read more

How nanocrystal structures self assemble Researchers at MIT and the Cornell High Energy Synchrotron Source (CHESS) have discovered some of the secrets to a long-hidden magic trick behind the self-assembly of nanocrystal structures, the understanding of which could be used to create more vivid display screens and optical sensory devices. The transformation of simple colloidal particles — b... » read more

Manufacturing Bits: March 8

5G mmWave consortium Amid a slowdown in the cell phone business, the market is heating up for perhaps the next big thing in wireless—5th generation mobile networks or 5G. Carriers, chipmakers and telecom equipment vendors are all rushing to get a piece of the action in 5G, which is the follow-on to the current wireless standard known as 4G or long-term evolution (LTE). Radio-frequency (RF... » read more

Glimpsing pathway of sunlight to electricity According to University of Oregon and Lund University researchers, four pulses of laser light on nanoparticle photocells in a University of Oregon spectroscopy experiment have opened a window on how captured sunlight can be converted into electricity. The work, which the researchers expect could inspire devices with improved efficiency in solar e... » read more

Origami Robots It may sound like something out of the movie Transformers, but MIT and Harvard have created origami robots that be reconfigured using timed sequencing. The robots were built from laser-cut parts using five layers of materials. A layer of etched copper is embedded between two structural layers of paper, with outer layers made of a polymer that folds when heated, according to... » read more
