The EU research project GECCO with their partners from Madrid, Bristol, Lodz, as well as Osram aim at vertically oriented LEDs that can boost the light output by a factor of 10. The European scientists expect that new three-dimensional assembly of LEDs could dramatically multiply the light output compared to today's planar devices. Currently, LEDs are being constructed in a planar way, meaning in layers and completely flat. The more light is being required, the more wafer area has to be produced—an expensive and laborious approach. The idea of the...
