Research Abstract |
This research project aims to fabricate and evaluate light-emitting diodes (LEDs) grown on a semipolar InGaN template enabling to realize state-of-the-art LED. Efficiency of a liquid crystal display using LEDs and laser diodes (LDs) can be improved by controlling light-polarization characteristics; it was revealed that the semipolar InGaN templates can control the light-polarization for the LEDs and LDs. Although LEDs recently have a problem of efficiency droop at a high-injection current, InGaN template is also effective to enhance the light output power of LED. The light output power of the LED fabricated on the InGaN template is approximately 6 times higher than that of a conventional LED at a high injection current.
