Graphene photodetector integrated into computer chip
The novel material graphene and its technological applications are studied at the Vienna University of Technology. Now scientists have succeeded in combining graphene light detectors with semiconductor chips. Today, most information is transmitted by light – for example in optical fibres. Computer chips, however, work electronically. Somewhere between the optical data highway and the electronic […]
Superconductivity to meet humanity’s greatest challenges
The stage is now set for superconductivity to branch out and meet some of the biggest challenges facing humanity today. This is according to a topical review `Superconductivity and the environment: a Roadmap’, published today, 16 September, in IOP Publishing’s journal Superconductor Science and Technology, which explains how superconducting technologies can move out of laboratories […]
New magnetic semiconductor material holds promise for spintronics
Researchers at North Carolina State University have created a new compound that can be integrated into silicon chips and is a dilute magnetic semiconductor – meaning that it could be used to make “spintronic” devices, which rely on magnetic force to operate, rather than electrical currents. The researchers synthesized the new compound, strontium tin oxide […]
Researchers read the coffee grounds and find a promising energy resource for the future
What’s usually considered old garbage might be a promising asset for our energy supply, according to University of Cincinnati researchers. For many of us, it’s the fuel that wakes us up and gets us started on our day. Now, University of Cincinnati researchers are discovering that an ingredient in our old coffee grounds might someday […]
Tool created to avert future energy crisis
Measurement tool created by UC Riverside assistant professor also helps better prepare the electricity market for the smart grid RIVERSIDE, Calif.— A University of California, Riverside assistant professor of electrical engineering and several colleagues have created a new measurement tool that could help avoid an energy crisis like the one California endured during the early […]
New kind of ultraviolet LED could lead to portable, low-cost devices
Light shines bright at precise frequencies that suit commercial applications COLUMBUS, Ohio—Commercial uses for ultraviolet (UV) light are growing, and now a new kind of LED under development at The Ohio State University could lead to more portable and low-cost uses of the technology.
