Figure 4From: Large enhancement of light extraction efficiency in AlGaN-based nanorod ultraviolet light-emitting diode structuresRadiation patterns in the nanorod LED structure. Electric field intensity distribution of light emitted from the dipole source is shown for (a) the TE and (b) TM modes when the p-GaN thickness is 100 nm. The color scale bar represents relative strength of electric field intensity.Back to article page
