All-inorganic perovskite quantum dot light-emitting memories
By Technical Paper Link - 18 Nov, 2021 - Comments: 0

Abstract "Field-induced ionic motions in all-inorganic CsPbBr3 perovskite quantum dots (QDs) strongly dictate not only their electro-optical characteristics but also the ultimate optoelectronic device performance. Here, we show that the functionality of a single Ag/CsPbBr3/ITO device can be actively switched on a sub-millisecond scale from a resistive random-access memory (RRAM) to a light-e... » read more

Roadmap on organic–inorganic hybrid perovskite semiconductors and devices
By Technical Paper Link - 03 Nov, 2021 - Comments: 0

ABSTRACT Metal halide perovskites are the first solution processed semiconductors that can compete in their functionality with conventional semiconductors, such as silicon. Over the past several years, perovskite semiconductors have reported breakthroughs in various optoelectronic devices, such as solar cells, photodetectors, light emitting and memory devices, and so on. Until now, perovskit... » read more

Neural network chip Neural networks are both slow and consume a lot of power. This made researchers at MIT examine the important aspects of the nodes within a neural network and to see how each part of the computation could be improved. The outcome was a dedicated chip that increases the speed of neural-network computations by three to seven times over its predecessors, while reducing power c... » read more

Singing to your storage Existing research on 'racetrack memory', which uses tiny magnetic wires, each one hundreds of times thinner than a human hair, down which magnetic bits of data run like racing cars around a track, has focused on using either magnetic fields or electric currents to move the data bits down the wires. However, both these options create heat and reduce power efficiency. ... » read more

Elastic energy harvesting Researchers from the Korea Advanced Institute of Science and Technology (KAIST) and Seoul National University collaborated to develop a hyper-stretchable elastic-composite energy harvesting device. Their stretchable piezoelectric generator can harvest mechanical energy to produce a ~4V power output with around 250% elasticity and a durability over 104 cycles. The... » read more
