Lower-cost metal 3-D printing solution available

3D printing of plastic parts to prototype or manufacture goods is becoming commonplace in industry, but there is an urgent need for lower-cost 3D printing technology to produce metal parts. New substrate release solutions ...

Ripple patterns in silicon can enhance solar cell efficiency

A*STAR scientists have produced a uniform nanoscale ripple pattern over a wide area on a silicon surface by scanning a femtosecond laser beam across it. Given that a rippled surface is much less reflective than a smooth surface, ...

Researchers develop powerful, silicon-based laser

A silicon-based laser that lases up to a record 111°C, with a threshold current density of 200 A/cm2 and an output power exceeding 100 mW at room temperature, has been demonstrated by collaborating researchers from University ...

DARPA program "grows" lasers directly on silicon-based microchips

DARPA's Electronic-Photonic Heterogeneous Integration (E-PHI) program has successfully integrated billions of light-emitting dots on silicon to create an efficient silicon-based laser. The breakthrough, achieved by researchers ...
