New light to illuminate the world

  • 摘要: 2014年诺贝尔物理学奖授予为开发GaN基高亮度蓝光发光二极管(LED)而做出先驱性工作的三位科学家。作者在阐释了这三位科学家的获奖理由以及蓝光LED对人类社会的重要意义后,简要回顾了获奖人在上世纪80年代至90年代针对蓝光LED这一技术难题,从技术路线的选择,到关键技术瓶颈的突破,再到最后取得成功所做的艰苦卓绝的工作。最后,作者还讨论了蓝光LED在带动产业发展和学科发展上的重要意义。

     

    Abstract: The Nobel Prize in Physics of 2014 was awarded to the three scientists who did the pioneering work for development of high-brightness GaN-based blue light-emitting diodes (LEDs). In this article, the award-winning grounds of the three scientists and the significance of blue LED on human society were interpreted firstly. Then, it was reviewed briefly that the arduous work did by the winners in the 1980s-1990s to develop the blue LED, including initial technical route selection, the breakthroughs of key technical bottlenecks, and the final success.Last, the significance of the blue LED to drive development of industry and academy were also discussed.
