Science Daily June 13, 2022 An international team of researchers (USA – MIT, University of Cincinnati, Harvard University, Stanford University, Washington University, Lawrence Berkeley National Laboratory, Lawrence Berkeley National Laboratory, South Korea, China) has developed stackable and replaceable hetero-integrated chips that use optoelectronic device arrays for chip-to-chip communication and neuromorphic cores based on memristor crossbar arrays for highly parallel data processing. They created a system with these chips that can directly classify information from a light-based image source.The system was modified by inserting a preprogrammed neuromorphic denoising layer that improves the classification performance in a noisy environment. Their technology can […]

Building a silicon quantum computer chip atom by atom (w/video)
Nanowerk January 12, 2022 Until now, implanting atoms in silicon has been a haphazard process, where a silicon chip gets showered with phosphorus which implant in a random pattern. An international team of researchers (Australia, Germany) has developed a technique to place them in an orderly array, similar to the transistors in conventional semiconductors computer chips. They embedded phosphorus ions, precisely counting each one, in a silicon substrate creating a qubit using advanced technology developed for sensitive x-ray detectors and a special atomic force microscope. They drilled a tiny hole in the cantilever, so that when it was showered with phosphorus […]
Electronic components join forces to take up 10 times less space on computer chips
Science Daily August 10, 2020 An international team of researchers (USA – University of Illinois, China) used specialized etching and lithography process to pattern 2D circuitry onto very thin membranes joining the capacitors, inductors, with signal lines, all in a single plane. Then rolled into a thin tube and placed onto a chip. The circuitry can be tuned to achieve the needed electrical interactions for a particular device. They found the filters to be suitable for applications in the 1-10 gigahertz frequency range. According to the team the filters can be designed for other frequencies, including in the megahertz range…read […]
