Figure 5From: Large enhancement of light extraction efficiency in AlGaN-based nanorod ultraviolet light-emitting diode structuresLEE versus structural parameters of the nanorod LED structure. (a) LEE is plotted as a function of the diameter of a nanorod when the rod height is 1,000 nm. (b) LEE is plotted as a function of the height of a nanorod when the rod diameter is 260 nm. Results for the TE and TM modes are represented as black and red dots, respectively.Back to article page
