Diodes allow electricity to flow in only one direction, protecting and controlling circuits. This video explains how they ...

When cooled to its superconducting state, niobium blocks the radiative flow of heat 20 times better than when in its metallic ...

This post features biographies and notable quotes from oral history interviews with planetary geophysicist Lynnae Quick, ...

In ‘Free-space optical communications at 4Gbit/s data rate with a terahertz laser’ , published in Communications Physics , ...

Silicon semiconductors are widely used as particle detectors; however, their long-term operation is constrained by performance degradation in high-radiation environments. Researchers at University of ...

Solar cells are an indispensable plank of the renewable energy transition, but they have an obvious limitation — they are useless at night. To fill this gap, scientists are exploring solar-cell-like ...

Scientists from the RIKEN Center for Emergent Matter Science and colleagues have developed a new way to fabricate three-dimensional nanoscale devices ...

A Penn State team has shattered Kirchhoff’s 165-year-old law of thermal radiation. Their engineered metamaterial emits more ...

Molecular electronic devices using quantum tunneling could achieve integration densities 1,000 times greater than silicon chips by combining atomic-precision assembly with three-dimensional ...

While it has become a word, laser used to be an acronym: “light amplification by stimulated emission of radiation”. But there is an even older technology called a maser, which is the ...

Silicon carbide is for photonic circuits and quantum devices. Atomic layer processing boosts SiC waveguides and resonators, improving performance.
