Spin polarization achieved in room temperature silicon

(PhysOrg.com) -- A group in The Netherlands has achieved a first: injection of spin-polarized electrons in silicon at room temperature. This has previously been observed only at extremely low temperatures, and the achievement ...

Nanotechnologists form near-frictionless diamond material

Researchers at the University of Pennsylvania, the University of Wisconsin-Madison and IBM Research-Zürich have fabricated an ultra sharp, diamond-like carbon tip possessing such high strength that it is 3,000 times more ...

'Nanospears' could lead to better solar cells, lasers, lighting

(PhysOrg.com) -- Growing - and precisely aligning - microscopic, spear-shaped zinc oxide crystals on a surface of single-crystal silicon, researchers at Missouri University of Science and Technology may have developed a method ...

Infrared encoding of images with metasurfaces

Researchers at MINAO, a joint lab between The French Aerospace Lab in Palaiseau and the Laboratoire de Photonique et de Nanostructures in Marcoussis, have recently demonstrated metamaterial resonators that allow emission ...

Silicon oxide memories transcend a hurdle
