“By fabricating ridges coated with silicon dioxide (SiO2) on the surface of a semiconductor, scientists from the National Institute of Advanced Industrial Science and Technology (AIST) in Japan have shown how to extract light from a semiconductor with an extremely high efficiency. The new technique could lead to the development of low-cost, ultra-high efficiency LEDs [...]
