In the future, the light-emitting diodes (LEDs) are expected to fully penetrate into the lighting market. A tremendous amount of energy will be saved through the LED-based lighting. Apparently, the amount of the energy saving strongly depends on the efficiency of the LEDs: this dissertation is all about the efficiency.

520 $a In the future, the light-emitting diodes (LEDs) are expected to fully penetrate into the lighting market. A tremendous amount of energy will be saved through the LED-based lighting. Apparently, the amount of the energy saving strongly depends on the efficiency of the LEDs: this dissertation is all about the efficiency.
520 $a First, the III-nitride LEDs grown on free-standing semipolar (202¯1¯) GaN substrates will be discussed. In many studies, LEDs grown on semipolar III-nitride substrates exhibited high efficiency at high current density. In this dissertation, "droop-free" (202¯1¯) blue LEDs will be demonstrated, especially for the standard industrial chip size.
520 $a In addition, contact optimization process for (202¯1¯) LEDs will be discussed. Series resistance of the (202¯1¯) LED devices has been improved through the contact optimization. As a result, the wall-plug efficiency (WPE) of the device was boosted by &sim;50%, compared to that of the previously reported (202¯1¯) LEDs.
520 $a Also, chip shaping for the semipolar LEDs to enhance the extraction efficiency will be covered as well. A new mesa design will be introduced, and the cleaving scheme for semipolar LED wafers will be thoroughly discussed.
520 $a Lastly, as a future work, selective area growth of ZnO light extraction features will be introduced and its preliminary result will be demonstrated.
