    Two scientists have developed a theory that adding light during the manufacturing of semiconductors—the materials that make up the essential parts of computer chips, solar cells and light emitting diodes (LEDs)—can reduce defects and potentially make more efficient solar cells or brighter LEDs. The role of light in semiconductor manufacturing may help explain many puzzling differences between processing methods as well as unlock the potential of materials that could not be used previously.

    that is pretty cool! I'm curious to know the actual mechanism behind this - I wouldn't have thought light could have such an impact

    Using light for doping?

    Doping is the process of adding impurities to intrinsic semiconductors to alter their properties.
