Stress and strain, applied in just the right manner, can sometimes produce amazing results. That is what researchers, led by a team at UC Berkeley’s Department of Electrical Engineering and Computer Sciences, discovered about an emerging semiconductor material—black phosphorous (BP)—used to make two types of optoelectronic devices: light emitting diodes (LEDs) and photodetectors.

Under mechanical strain, BP can be induced to emit or detect infrared (IR) light in a range of desirable wavelengths—2.3 to 5...

Physics researchers at the University of North Florida’s Atomic LEGO Lab discovered a new electronic phenomenon they call ” asymmetric ferroelectricity .” The research led by Dr. Maitri Warusawithana, UNF physics assistant professor, in collaboration with researchers at the University of Illinois and the Arizona State University, demonstrated this phenomenon for the first time in engineered two-dimensional crystals.

This discovery of asymmetric ferroelectricity in engineered crystals comes exactly 100 years following the discovery of ferroelectricity in certain naturally occurring crystals...

A new algorithm helps drones find the fastest route around obstacles without crashing. The system could enable fast, nimble drones for time-critical operations such as search and rescue.

If you follow autonomous drone racing, you likely remember the crashes as much as the wins. In drone racing, teams compete to see which vehicle is better trained to fly fastest through an obstacle course. But the faster drones fly, the more unstable they become, and at high speeds their aerodynamics can be too complicated to predict...

A team of scientists has developed a means to create a new type of memory, marking a notable breakthrough in the increasingly sophisticated field of artificial intelligence.

“Quantum materials hold great promise for improving the capacities of today’s computers,” explains Andrew Kent, a New York University physicist and one of the senior investigators. “The work draws upon their properties in establishing a new structure for computation.”

The creation, designed in partnership with researchers from the University of California, San Diego (UCSD) and the University of Paris-Saclay, is reported in Scientific Reports.

“Since conventional computing has reached its limits, new computational methods and devices are being developed,” adds Ivan Schuller, a UCSD physicist and one of the...
