Samsung and IBM Could Break the Nanosheet Threshold in Chips With ‘Vertically Stacked Transistors’ – IBM & Samsung Indicate This Could DOUBLE Processor Performance (MIT/ NTU)

This design can either double the performance of chips or reduce power use by 85%. In May of 2021, we brought you a breakthrough in semiconductor materials that saw the creation of a chip that could push back the “end” of Moore’s Law and further widen the capability gap between China and U.S.-adjacent efforts in the field of 1-nanometer chips. Now, IBM and Samsung claim they have also made a…

Like graphene (the two-dimensional honeycomb form of carbon), silicon forms atom-thick networks known as nanosheets. Now, researchers at the Technical University of Munich (TUM), Germany, have embedded these sheets into a polymer for the first time, physically stabilising the nanosheets and protecting them from decay and oxidation.

‘Silicon nanosheets are particularly interesting because today's information technology builds on silicon and, unlike with graphene, the basic material does not need to be exchanged,’ explains Tobias Helbich from the WACKER Chair for Macromolecular Chemistry at TUM. ‘However, the nanosheets themselves are very delicate and quickly disintegrate when exposed to UV light, which has significantly limited their application thus far.’ 

The nanosheets could be used in flexible displays, field-effect transistors and, because of silicon’s ability to store lithium ions, are being considered as an anode material for rechargeable batteries. 

In fact, colleagues at TUM’s Institute of Nanoelectronics have already built a working photodetector based on the new nanosheets.  

Enhanced ambient ammonia photosynthesis using nanosheets with light-switchable oxygen vacancies

Researchers have presented a strategy by simultaneously introducing light-switchable oxygen vacancy and doping mo into Bi5O7Br nanosheets for efficient photocatalytic N2 fixation. The modified photocatalyst has achieved elevated N2 fixation photoactivities by virtue of the optimized conduction band position, enhanced light availability, improved N2 adsorption and charge carrier separation.…
