Nano-LEDs emit full visible spectrum of light

(PhysOrg.com) -- Physicists from Taiwan have designed and fabricated nano-sized light-emitting diodes (LEDs) that emit light spanning the entire visible spectrum. Although the tiny full-color LEDs aren't intended for commercial ...

New, Unusual Semiconductor is a Switch-Hitter

(PhysOrg.com) -- A research group in Germany has discovered a semiconducting material that can switch its semiconducting properties -- turning from one type of semiconductor to another -- via a simple change in temperature. ...

Revolutionary solar-friendly form of silicon shines

Silicon is the second most-abundant element in the earth's crust. When purified, it takes on a diamond structure, which is essential to modern electronic devices—carbon is to biology as silicon is to technology. A team ...

Disorder can improve the performance of plastic solar cells

Scientists have spent decades trying to build flexible plastic solar cells efficient enough to compete with conventional cells made of silicon. To boost performance, research groups have tried creating new plastic materials ...
