New method to make gallium arsenide solar cells

(PhysOrg.com) -- A new "transfer-printing" method of making light-sensitive semiconductors could make solar cells, night-vision cameras, and a range of other devices much more efficient, and could transform the solar industry.

First germanium laser brings us closer to 'optical computers'

(PhysOrg.com) -- MIT researchers have demonstrated the first laser built from germanium that can produce wavelengths of light useful for optical communication. It’s also the first germanium laser to operate at room temperature. ...

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 ...
