Researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have created a chip-scale device ...

A new liquid crystal device lets scientists control how light twists and behaves using voltage, making it possible to reshape light patterns without changing the physical structure of the device.

Engineers have succeeded in fabricating a giant magnetoresistive (GMR) device comprising single-crystal Heusler alloys on an practical silicon substrate. The team demonstrated for the first time that ...

A micrometre-sized device that produces light by firing a beam of electrons over a slab of crystal could be used to build tiny particle accelerators and X-ray machines. Such chip-sized devices could ...
