All-inorganic perovskite quantum dot light-emitting memories


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

Materials and Device Simulations for Silicon Qubit Design and Optimization


Abstract: "Silicon-based microelectronics technology is extremely mature, yet this profoundly important material is now also poised to become a foundation for quantum information processing technologies. In this article, we review the properties of silicon that have made it the material of choice for semiconductor-based qubits with an emphasis on the role that modeling and simulation have play... » read more

Recovery In Flat-Panel Display Biz


The flat-panel display market is starting to recover after a period of oversupply and lackluster growth, fueled by new technologies as well as more people working from home. The flat-panel display market is complex. Several different technologies are at play, such as liquid-crystal displays (LCDs) for TV screens and other products, as well as organic light-emitting diodes (OLEDs) for smartph... » read more

System Bits: July 30


A camera that sees around corners Researchers at Stanford University developed a camera system that can detect moving objects around a corner, looking at single particles of light reflected on a wall. “People talk about building a camera that can see as well as humans for applications such as autonomous cars and robots, but we want to build systems that go well beyond that,” said Gordon... » read more

Creating 2D Compounds


A 2D material, by definition, has no surface dangling bonds. A bulk material with plate-like structure, such as graphite, is composed of thin layers with a weakly bonded cleavage plane between. What this means is a monolayer of graphite will seek to satisfy its exposed dangling bonds by absorbing other materials. A monolayer of graphene, in contrast, is energetically complete without a secon... » read more

Inside The Quantum Dot


Quantum dots, a relatively new and emerging technology, are creating a buzz in the industry. Basically, when inserted into an LCD TV, quantum dots can boost the color gamut in the display, enabling vivid picture quality with relatively little capital. Quantum dots can also be used in other applications, such as solar and LED lighting. To get a handle on the technology, Semiconductor Enginee... » read more
