What substance did Shuji Nakamura utilize to bridge the material science gap and create the high-brightness blue LED?
Answer
Gallium Nitride (GaN)
Shuji Nakamura focused on Gallium Nitride (GaN) as the material, refining the growth process, often involving Indium Gallium Nitride (InGaN), to finally produce usable bright blue emitters.
