2014 Nobel Prize in Physics

Blue light-emitting diodes (LEDs) are everywhere — smartphones, computer screens, energy-efficient light bulbs — and that’s thanks to the efforts of three Japanese-born inventors who have now been awarded the 2014 Nobel Prize in Physics. Working through the 1980s and 1990s, Isamu Akasaki, Hiroshi Amano and Shuji Nakamura overcame several technological hurdles to coax a semiconductor into emitting high-power blue light.

In celebration, NPG is making available a range of articles from its journal archives that capture and reflect their remarkable achievements. Due to their impact and importance the research articles in the Highlights section will be free to access for a month.
