Hace 22 horas · The corresponding author of this work, Hiroshi Amano, and Isamu Akasaki of Nagoya University created the first blue-light LEDs using Mg-doped GaN in the late 1980s. Their efforts, for which they were awarded the 2014 Nobel Prize in Physics, have been crucial in fostering a civilization that uses less energy.
Hace 2 días · Isamu Akasaki, Hiroshi Amano, and Shuji Nakamura made groundbreaking contributions to GaN-based blue LEDs and laser diodes. Their work overcame significant challenges related to the material's crystal growth and doping, leading to the development of the first practical blue LEDs in the early 1990s.
