Heterostructures support predictions of counterpropagating charged edge modes at the v=2/3 fractional quantum Hall state — ScienceDaily
In 2018, a team of physicists at Purdue University invented a device which experimentally showed quasiparticles interfering for the first time in the fractional quantum Hall effect at filling factor v=1/3. Further development of these heterostructures has allowed the Manfra Group to expand their research to experiments that explore counterflowing charged edge modes at the…

Team creates single-photon emitters exactly where they are needed — ScienceDaily
In the very near future, quantum computers are expected to revolutionize the way we compute, with new approaches to database searches, AI systems, simulations and more. But to achieve such novel quantum technology applications, photonic integrated circuits which can effectively control photonic quantum states — the so-called qubits — are needed. Physicists from the Helmholtz-Zentrum…

Watch Syntiant’s 1-Milliwatt Chip Play Doom
There are many things to do with an always-on 1-milliwatt machine-learning chip, but few spark the imagination quite like watching it play Doom. At the 2023 IEEE International Solid State Circuits Conference (ISSCC) in San Francisco this week, Irvine, Calif.–based Syntiant detailed the NDP200. This is an ultralow-power chip designed to run neural networks that…

How Smart Semiconductor Technology Will Improve Personal Health
This sponsored article is brought to you by Infineon Technologies. We live in a world of rising population. The latest projections by the United Nations suggest that the global population could grow to around 8.5 billion in 2030 and 9.7 billion in 2050. At the same time, life expectancy is increasing. If the global average…

Ultrafast Terahertz Tech Via Electronic Metadevices
Ultraquick telecommunications at terahertz frequencies are now possible using “electronic metadevices,” which may set the stage for the next generation of speedy gadgets. The way in which these novel devices control electric fields is similar to how invisibility cloaks manipulate light, heat, and sound, a new study finds. As electronics shrink, following Moore’s Law, they…

This new sensor can detect mercury ions with just a tap — ScienceDaily
Although many measures are in place to prevent contamination, pollutants, such as mercury and lead, can still end up in the environment. Sensing them often requires complicated processes, but what if you could detect them with the tap of a fingertip? Researchers reporting in ACS Nano have developed a self-powered nanosensor that can discover small…

Creating an efficient, cost-effective, and flexible solar energy harvesting design based on self-assembled nanoparticles — ScienceDaily
Solar-thermal technology is a promising environmentally friendly energy harvesting method with a potential role to play in solving the fossil fuel energy crisis. The technology transforms sunlight into thermal energy, but it’s challenging to suppress energy dissipation while maintaining high absorption. Existing solar energy harvesters that rely on micro- or nanoengineering don’t have sufficient scalability…

These sports sensors could curb ‘bad calls’ and help players during practices — ScienceDaily
If you watched the most recent Super Bowl, you know the importance of a referee’s call on the outcome of a game. Slow-motion replays and close-watching eyes help, but a new sensor technology could someday serve as an even more reliable tool for officials. Researchers reporting in ACS Applied Nano Materials have developed a self-powered,…
