The new design is stackable and reconfigurable, for swapping out and building on existing sensors and neural network processors. Imagine a more sustainable future, where cellphones, smartwatches, and other wearable devices don’t have to be shelved or discarded for a newer model.

Instead, they could be upgraded with the latest sensors and processors that would snap onto a device’s internal chip — like LEGO bricks incorporated into an existing build. Such reconfigurable chipware could keep devices up to date while reducing our electronic waste.

Three teams of researchers at Clemson University have joined forces to unravel some of the mysteries surrounding perovskite nanocrystals, which are semiconductors with numerous applications, including LEDs, lasers, solar cells and photodetectors.

A research article titled “The correlation between phase transition and photoluminescence properties of CsPbX3 (X=Cl, Br, I) perovskite nanocrystals” recently appeared in Nanoscale Advances, an open-access journal published by the Royal Society of Chemistry...

Single nanocrystal spectroscopy identifies the interaction between zero-dimensional CdSe/ZnS nano crystals (quantum dots) and two-dimensional layered tin disulfide as a non-radiative energy transfer, whose strength increases with increasing number of tin disulfide layers. Such hybrid materials could be used in optoelectronic devices such as photovoltaic solar cells, light sensors, and LEDs. Credit: Brookhaven National Laboratory

It paves the way for better optoelectronic apps eg energy-harvesting photovoltaics, light sensors, LEDs. Scientists combined excellent light-harvesting properties of quantum dots with the tunable electrical conductivity of a layered tin disulfide semiconductor...
