Power/Performance Bits: Feb. 4


Lead halide perovskites Paving the way to the design of photovoltaic converters with improved efficiency, researchers at Ecole Polytechnique Fédérale de Lausanne (EPFL) said they have uncovered the mechanism by which solar cells based on lead iodide perovskite light-absorbing semiconductor transfer electrons along their surface. Photovoltaic systems based on lead halide perovskite are a n... » read more

Tunnel FETs Emerge In Scaling Race


Traditional CMOS scaling will continue for the foreseeable future, possibly to the 5nm node and perhaps beyond, according to many chipmakers. In fact, chipmakers already are plotting out a path toward the 5nm node, but needless to say, the industry faces a multitude of challenges along the road. Presently, the leading transistor candidates for 5nm are the usual suspects—III-V finFETs; gate... » read more

System Bits: Oct. 22


Untangled nanotubes Carbon nanotubes are lightweight, strong and conduct electricity, which make them ideal components in new electronics devices, such as tablet computers and touchscreen phones, but cannot be used without being separated out from their natural tangled state. Researchers from Imperial College London have developed a way to unravel and apply carbon nanotubes in the laboratory a... » read more

Power/Performance Bits: Oct. 15


Perfect ICs Are integrated circuits "too good" for current technological applications? Christian Enz, the new director of the Institute of Microengineering at Ecole Polytechnique Fédérale de Lausanne (EPFL) believes perfection is overrated. Enz said the reason why we should build our future devices with unreliable circuits, and adopt the "good enough engineering" trend is that non-fully r... » read more

Manufacturing Bits: Aug. 13


Crawling And Climbing Robots The field of autonomous robotics is generating interest, as these systems can explore areas and perform functions that are risky and inaccessible to humans. The University of California at San Diego and EPFL separately have developed new autonomous robots for a range of applications. For example, UC San Diego has developed a robot designed to scoot along utility... » read more

Efficiency Vs. Accuracy


By Barry Pangrle If all you have is a hammer, everything looks like a nail. I wrote an article, Power vs. Accuracy, last year that discussed tradeoffs between power and accuracy for different applications. It turns out that for a number of processing applications, if every bit isn’t perfect, the impact on the final result might not be all that great. Anyone performing financial analytical... » read more
