Engineers create vibrant colors in vertical silicon nanowires

(PhysOrg.com) -- Engineers may soon be singing, "I'm going to wash that gray right out of my nanowires," thanks to a colorful discovery by a team of researchers from Harvard University and Zena Technologies. In contrast to ...

Single quantum dot nanowire photodetectors

Moving a step closer toward quantum computing, a research team in the Netherlands recently fabricated a photodetector based on a single nanowire, in which the active element is a single quantum dot with a volume of a mere ...

Combating counterfeiting: Advanced hologram protection invented

Counterfeiting of various documents, banknotes, or tickets is a common problem that can be encountered in everyday life, even when shopping. Recognizing the scale and seriousness of the problem, researchers at Kaunas University ...

Apochromatic X-ray focusing

A team of scientists from the Paul Scherrer Institut, the University of Basel and DESY have demonstrated the first-ever realization of apochromatic X-ray focusing using a tailored combination of a refractive lens and a Fresnel ...

'Plug-and-play' plasmonic metafibers for ultrafast fiber lasers

Integrating plasmonic metasurfaces on optical fiber tips forming so-called metafibers enriches the functionalities of an ordinary optical fiber, yielding a variety of advanced applications such as planar waveshaping, super-resolution ...
