Abstract

In the work reported here we use the finite-difference time-domain method to model an ordered nanorod array incorporated in a vertical LED structure in place of the surface roughened region. The simulations reveal that diffraction dominates the far field emission when the emissive layer lies below the nanorod array, as might occur in a vertical LED structure with the NR layer used as a light extracting element in place of a roughened surface.
