Objectives
Breakthroughs in the growth and doping of GaN materials in the 1990s led to the discovery of the elusive blue light-emitting diode (LED), which rapidly evolved into solid-state lighting products that became widely adopted within 20 years of its invention. The III-V material and its alloys are not only suitable for manufacturing LEDs but is also ideal for the development of visible/ultraviolet laser diodes which are in huge demand for applications including printing, spectroscopy and projection displays.
