Why GaN-Based LED?<br />
Vegard’s law<br />
for In x Ga 1-x N<br />
Eg InGaN = xEg InN + (1-x)Eg GaN<br />
a InGaN = xa InN + (1-x)a GaN<br />
Since Nakamura at Nichia invented blue LEDs from InGaN in 1993, fullcolor<br />
LEDs have been achieved. With high luminous efficiency (70%)<br />
and long lifetime over 10 5 hours, InGaN-related LEDs have been<br />
meteoric for 15 years.
