Tweaking quantum dots powers-up double-pane solar windows

Using two types of "designer" quantum dots, researchers are creating double-pane solar windows that generate electricity with greater efficiency and create shading and insulation for good measure. It's all made possible by ...

Team finds the 'key' to quantum network solution

Scientists at the University of York's Centre for Quantum Technology have made an important step in establishing scalable and secure high rate quantum networks.

Terahertz spectroscopy enters the single-molecule regime

The interaction of light with matter is the basis of spectroscopy, a set of techniques lying at the heart of physics and chemistry. From infrared light to X-rays, a broad sweep of wavelengths is used to stimulate vibrations, ...

Speedy terahertz-based system could detect explosives

Terahertz spectroscopy, which uses the band of electromagnetic radiation between microwaves and infrared light, is a promising security technology because it can extract the spectroscopic "fingerprints" of a wide range of ...

Metamaterial uses light to control its motion

Researchers have designed a device that uses light to manipulate its mechanical properties. The device, which was fabricated using a plasmomechanical metamaterial, operates through a unique mechanism that couples its optical ...

Nanocrystals emit light by efficiently 'tunneling' electrons

Using advanced fabrication techniques, engineers at the University of California San Diego have built a nanosized device out of silver crystals that can generate light by efficiently "tunneling" electrons through a tiny barrier. ...
