Figure 1From: Large enhancement of light extraction efficiency in AlGaN-based nanorod ultraviolet light-emitting diode structuresSchematic diagram of FDTD computational domain. Side view of the simulated LED structure is shown for (a) the planar LED and (b) nanorod LED structures. PMLs are employed for the absorption boundary condition of the FDTD simulation. The detection plane for extracted light is indicated as dotted red line. (c) Cross-sectional view of the simulated nanorod LED structure.Back to article page
