A gentler, more precise laser cutting technique

Laser cutting techniques are usually powered by high energy beams, so hot that they melt most materials. Now scientists from McGill University have developed a gentler, more precise technique using low-power visible light.

Making dark semiconductors shine

Whether or not a solid can emit light, for instance as a light-emitting diode (LED), depends on the energy levels of the electrons in its crystalline lattice. An international team of researchers led by University of Oldenburg ...
