Supercomputers around the world At last week’s International Supercomputing Conference in Frankfurt, Germany, the 53rd biannual list of the Top500 of the most powerful computing systems in the world was released. Broken out by countries of installation, China has 219 of the world’s 500 fastest supercomputers, compared with 116 in the United States. Ranking by percent of list flops, the ... » read more

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

Predicting warpage in packages At the recent IEEE Electronic Components and Technology Conference (ECTC) in Las Vegas, there were several papers on ways to predict variation and warpage in IC packages. Advanced packages are prone to unwanted warpage during the process flow. The warpage challenges escalate as the packages become thinner. Warpage in turn can impact yields in IC packages. ... » read more

SlothBot swings through the trees, slowly A robot that doesn’t often move, spending its days, weeks, months, in the forest canopy, monitoring the local environment – that’s SlothBot, from the Georgia Institute of Technology. The robot has two photovoltaic solar panels for its power source. It is designed to stay in the trees for months at a time. It’s gone through trials on the Geor... » read more

Quantum dots plus perovskites Researchers at the University of Toronto and KAUST created a hybrid material for solar cells that utilizes both perovskites and quantum dots. Both quantum dots and perovskites suffer from instability: perovskites degrade quickly and certain types become incapable of fully absorbing solar radiation at room temperature, while quantum dots must be covered with a p... » read more
