Optical manipulation not just a phase for 2D materials

Materials Today: Optical manipulation at the nanoscale, or nanophotonics, has become a critical research area, as researchers seek ways to meet the ever-increasing demand for information processing and communications. The ability to control and manipulate light at the nanometer scale will…

Image Sensor Doubles as a Neural Net

IEEE Spectrum: A new ultra-fast machine-vision device can process images thousands of times faster than conventional techniques with an image sensor that is also an artificial neural network. Machine vision technology often uses artificial neural networks to analyze images. In artificial neural networks, components dubbed “neurons” are fed data and…

3nm: Blurring Lines Between SoCs, PCBs And Packages

Semiconductor Engineering: Leading-edge chipmakers, foundries and EDA companies are pushing into 3nm and beyond, and they are encountering a long list of challenges that raise questions about whether the entire system needs to be shrunk onto a chip or into a…

Novel photovoltaics generate electrical power from thermal sources

Physics World: A new type of photovoltaic device can generate useful amounts of electrical power from sources that radiate heat at moderate temperatures. So say researchers at Sandia National Laboratories in the US, who succeeded in recovering power densities between 27–61…
