Power/Performance Bits: June 25


Improving IGBTs Researchers at the University of Tokyo developed a power switching device that surpasses previous performance limits, showing that there may still be gains ahead for the silicon-based devices, which have been thought to be approaching their limits. The team's improved insulated gate bipolar transistor (IGBT) used a scaling approach, and simulations showed that downscaling pa... » read more

Week in Review: IoT, Security, Auto


Internet of Things The Wing unit of Alphabet this summer will begin making drone deliveries in the Vuosarri district of Helsinki, Finland. The unmanned aerial vehicles will bear food and other items from Herkku Food, a gourmet market, and the Café Monami restaurant. The drones will bear deliveries of up to 3.3 pounds over distances of up to 6.2 miles. Comcast is reportedly developing an in... » read more

Radiation thermometers The National Institute of Standards and Technology (NIST) has developed a thermometer that can measure radiation within a few thousandths of a degree Celsius. The so-called Ambient-Radiation Thermometer (ART) from NIST is a new type of radiation thermometer, which measures infrared radiation (IR) given off by objects without touching them. Measuring 60 centimeters ... » read more

Week in Review: IoT, Security, Auto


Internet of Things AT&T reports the activation of its narrowband Internet of Things network in the U.S. The carrier upgraded its 4G LTE cell sites across the country. It now offers two low-power wide-area networks to business customers, including its LTE-M network in Mexico and the U.S. “Both networks are designed for the IoT within licensed spectrum and provide carrier-grade security,... » read more

Manufacturing Bits: April 30


Single-atom catalysts A group of researchers have captured the behavior of a single-atom catalyst, a move that could one day help design more efficient catalysts in systems. A catalyst is a substance that increases the rate of a chemical reaction. In vehicles, for example, platinum is used as a catalyst, which speeds up chemical reactions and cleans exhaust gases. Besides platinum, the indu... » read more

3D NAND Metrology Challenges Growing


3D NAND vendors face several challenges to scale their devices to the next level, but one manufacturing technology stands out as much more difficult at each turn—metrology. Metrology, the art of measuring and characterizing structures, is used to pinpoint problems and ensure yields for all chip types. In the case of 3D NAND, the metrology tools are becoming more expensive at each iteration... » read more

Power/Performance Bits: Mar. 26


Material holds both electrons, holes Researchers at Ohio State University discovered a material that can hold both electrons and holes. They hope the material, the layered metal crystal NaSn2As2, could simplify electronics, potentially removing the need for multiple layers or materials. "It is this dogma in science, that you have electrons or you have holes, but you don't have both. But our... » read more

System Bits: March 11


Cryptography IC for the IoT Massachusetts Institute of Technology researchers report their development of a cryptographic circuit that could be used to protect low-power Internet of Things devices when quantum computing takes hold.
