dc.description.abstractThe results of our analysis, which was done by using the finite-difference, time-domain (FDTD) methods suggest that surface-structured light-emitting diodes (LEDs) with a subwavelength aluminum-nitride coating will have an enhanced light extraction efficiency. The use of such a LED structure will reduce both the internal reflection and the impedance mismatch, leading to a 3.2-fold enhancement in the light extraction efficiency compared to that for bare planar LEDs. We also present an improved method of modeling the light emission from the LED's active layers to numerically calculate the light extraction efficiency of LEDs.-
