400-nm InGaN–GaN and InGaN–AlGaN Multiquantum Well Light-Emitting Diodes


Rcenctly, tremendous progress has been achieved in GaN-based blue and green light-emitting diodes (LEDs). These blue/green LEDs have already been extensively used in full-color displays and high-efficient light sources for traffic light lamps. Although these blue/green LEDs are already commercially available, it is still difficult to achieve LEDs emitting at even shorter wavelength regions, such as ultraviolet (UV) region..........[FULL STORY]
