Figure 7From: Large enhancement of light extraction efficiency in AlGaN-based nanorod ultraviolet light-emitting diode structuresLEE versus refractive index of AlGaN. LEE is plotted as a function of the refractive index of AlGaN material for the TE (black dots) and TM (red dots) modes. The diameter and height of simulated nanorods are 260 and 1,000 nm, respectively.Back to article page
